There was a change previously to stop SR-IOV and LAG from existing on the
same interface. This was to prevent the violation of LACP (Link
Aggregation Control Protocol). The method to achieve this was to add a
no-op Rx handler onto the netdev when SR-IOV VFs were present, thus
blocking bonding, bridging, etc from claiming the interface by adding
its own Rx handler. Also, when an interface was added into a aggregate,
then the SR-IOV capability was set to false.
There are some users that have in house solutions using both SR-IOV and
bridging/bonding that this method interferes with (e.g. creating duplicate
VFs on the bonded interfaces and failing between them when the interface
fails over).
It makes more sense to provide the most functionality
possible, the restriction on co-existence of these features will be
removed. No additional functionality is currently being provided beyond
what existed before the co-existence restriction was put into place. It is
up to the end user to not implement a solution that would interfere with
existing network protocols.

Replace custom interrupt tracker with generic xarray data structure.
Remove all code responsible for searching for a new entry with xa_alloc,
which always tries to allocate at the lowes possible index. As a result
driver is always using a contiguous region of the MSIX vector table.
New tracker keeps ice_irq_entry entries in xarray as opaque for the rest
of the driver hiding the entry details from the caller.

Currently interrupt allocations, depending on a feature are distributed
in batches. Also, after allocation there is a series of operations that
distributes per irq settings through that batch of interrupts.
Although driver does not yet support dynamic interrupt allocation, keep
allocated interrupts in a pool and add allocation abstraction logic to
make code more flexible. Keep per interrupt information in the
ice_q_vector structure, which yields ice_vsi::base_vector redundant.
Also, as a result there are a few functions that can be removed.

The ice_vsi_alloc and ice_vsi_cfg functions are used together to allocate
and configure a new VSI, called as part of the ice_vsi_setup function.
In the future with the addition of the subfunction code the ice driver
will want to be able to allocate a VSI while delaying the configuration to
a later point of the port activation.
Currently this requires that the port code know what type of VSI should
be allocated. This is required because ice_vsi_alloc assigns the VSI type.
Refactor the ice_vsi_alloc and ice_vsi_cfg functions so that VSI type
assignment isn't done until the configuration stage. This will allow the
devlink port addition logic to reserve a VSI as early as possible before
the type of the port is known. In this way, the port add can fail in the
event that all hardware VSI resources are exhausted.
Since the ice_vsi_cfg function already takes the ice_vsi_cfg_params
structure, this is relatively straight forward.

The ice_vsi_setup function, ice_vsi_alloc, and ice_vsi_cfg functions have
grown a large number of parameters. These parameters are used to initialize
a new VSI, as well as re-configure an existing VSI
Any time we want to add a new parameter to this function chain, even if it
will usually be unset, we have to change many call sites due to changing
the function signature.
A future change is going to refactor ice_vsi_alloc and ice_vsi_cfg to move
the VSI configuration and initialization all into ice_vsi_cfg.
Before this, refactor the VSI setup flow to use a new ice_vsi_cfg_params
structure. This will contain the configuration (mainly pointers) used to
initialize a VSI.
Pass this from ice_vsi_setup into the related functions such as
ice_vsi_alloc, ice_vsi_cfg, and ice_vsi_cfg_def.
Introduce a helper, ice_vsi_to_params to convert an existing VSI to the
parameters used to initialize it. This will aid in the flows where we
rebuild an existing VSI.
Since we also pass the ICE_VSI_FLAG_INIT to more functions which do not
need (or cannot yet have) the VSI parameters, lets make this clear by
renaming the function parameter to vsi_flags and using a u32 instead of a
signed integer. The name vsi_flags also makes it clear that we may extend
the flags in the future.
This change will make it easier to refactor the setup flow in the future,
and will reduce the complexity required to add a new parameter for
configuration in the future.

The vsi->vf pointer gets assigned early on during ice_vsi_alloc. Several
functions currently take a VF pointer, but they can just use the existing
vsi->vf pointer as needed. Modify these functions to drop the unnecessary
VF parameter.
Note that ice_vsi_cfg is not changed as a following change will refactor so
that the VF pointer is assigned during ice_vsi_cfg rather than
ice_vsi_alloc.

ice_vsi_cfg() is called from different contexts:
1) VSI exsist in HW, but it is reconfigured, because of changing queues
for example -> update instead of init should be used
2) VSI doesn't exsist, because rest has happened -> init command should
be sent
To support both cases pass boolean value which will store information
what type of command has to be sent to HW.

to remove VSI from hw without freeing the memory:

When allocating the ICE_VSI_CTRL, the allocated struct ice_vsi pointer is
stored into the PF's pf->vsi array at a fixed location. This was
historically done on the basis that it could provide an O(1) lookup for the
special control VSI.
Since we store the ctrl_vsi_idx, we already have O(1) lookup regardless of
where in the array we store this VSI.
Simplify the logic in ice_vsi_alloc by using the same method of storing the
control VSI as other types of VSIs.

Main goal is to reuse the same functions in VSI config and rebuild
paths.
To do this split ice_vsi_setup into smaller pieces and reuse it during
rebuild.
ice_vsi_alloc() should only alloc memory, not set the default values
for VSI.
Move setting defaults to separate function. This will allow config of
already allocated VSI, for example in reload path.
The path is mostly moving code around without introducing new
functionality. Functions ice_vsi_cfg() and ice_vsi_decfg() were
added, but they are using code that already exist.
Use flag to pass information about VSI initialization during rebuild
instead of using boolean value.

Do few small cleanups:
1) Rename the function to reflect that it doesn't configure all things
related to VSI. ice_vsi_cfg_lan() better fits to what function is doing.
ice_vsi_cfg() can be use to name function that will configure whole VSI.
2) Remove unused ethtype field from VSI. There is no need to set
ethtype here, because it is never used.
3) Remove unnecessary check for ICE_VSI_CHNL. There is check for
ICE_VSI_CHNL in ice_vsi_get_qs, so there is no need to check it before
calling the function.
4) Simplify ice_vsi_alloc() call. There is no need to check the type of
VSI before calling ice_vsi_alloc(). For ICE_VSI_CHNL vf is always NULL
(ice_vsi_setup() is called with vf=NULL).
For ICE_VSI_VF or ICE_VSI_CTRL ch is always NULL and for other VSI types
ch and vf are always NULL.
5) Remove unnecessary call to ice_vsi_dis_irq(). ice_vsi_dis_irq() will
be called in ice_vsi_close() flow (ice_vsi_close() -> ice_vsi_down() ->
ice_vsi_dis_irq()). Remove unnecessary call.
6) Don't remove specific filters in release. All hw filters are removed
in ice_fltr_remove_alli(), which is always called in VSI release flow.
There is no need to remove only ethertype filters before calling
ice_fltr_remove_all().
7) Rename ice_vsi_clear() to ice_vsi_free(). As ice_vsi_clear() only
free memory allocated in ice_vsi_alloc() rename it to ice_vsi_free()
which better shows what function is doing.
8) Free coalesce param in rebuild. There is potential memory leak if
configuration of VSI lan fails. Free coalesce to avoid it.

Rx path is going to be modified in a way that fragmented frame will be
gathered within xdp_buff in the first place. This approach implies that
underlying buffer has to provide tailroom for skb_shared_info. This is
currently the case when ring uses build_skb but not when legacy-rx knob
is turned on. This case configures 2k Rx buffers and has no way to
provide either headroom or tailroom - FWIW it currently has
XDP_PACKET_HEADROOM which is broken and in here it is removed. 2k Rx
buffers were used so driver in this setting was able to support 9k MTU
as it can chain up to 5 Rx buffers. With offset configuring HW writing
2k of a data was passing the half of the page which broke the assumption
of our internal page recycling tricks.
Now if above got fixed and legacy-rx path would be left as is, when
referring to skb_shared_info via xdp_get_shared_info_from_buff(),
packet's content would be corrupted again. Hence size of Rx buffer needs
to be lowered and therefore supported MTU. This operation will allow us
to keep the unified data path and with 8k MTU users (if any of
legacy-rx) would still be good to go. However, tendency is to drop the
support for this code path at some point.
Add ICE_RXBUF_1664 as vsi::rx_buf_len and ICE_MAX_FRAME_LEGACY_RX (8320)
as vsi::max_frame for legacy-rx. For bigger page sizes configure 3k Rx
buffers, not 2k.
Since headroom support is removed, disable data_meta support on legacy-rx.
When preparing XDP buff, rely on ice_rx_ring::rx_offset setting when
deciding whether to support data_meta or not.

Commit a286ba738714 ("ice: reorder PF/representor devlink
port register/unregister flows") moved the code to create
and destroy the devlink PF port. This was fine, but created
a corner case issue in the case of ice_register_netdev()
failing. In that case, the driver would end up calling
ice_devlink_destroy_pf_port() twice.
Additionally, it makes no sense to tie creation of the devlink
PF port to the creation of the netdev so separate out the
code to create/destroy the devlink PF port from the netdev
code. This makes it a cleaner interface.

Resets may occur with or without user interaction. For example, a TX hang
or reconfiguration of parameters will result in a reset. During reset, the
VSI is freed, freeing any statistics structures inside as well. This would
create an issue for the user where a reset happens in the background,
statistics set to zero, and the user checks ring statistics expecting them
to be populated.
To ensure this doesn't happen, accumulate ring statistics over reset.
Define a new ring statistics structure, ice_ring_stats. The new structure
lives in the VSI's parent, preserving ring statistics when VSI is freed.
1. Define a new structure vsi_ring_stats in the PF scope
2. Allocate/free stats only during probe, unload, or change in ring size
3. Replace previous ring statistics functionality with new structure

Resets happen with or without user interaction. For example, incidents
such as TX hang or a reconfiguration of parameters will result in a reset.
During reset, hardware and software statistics were set to zero. This
created an issue for the user where a reset happens in the background,
statistics set to zero, and the user checks statistics expecting them to
be populated.
To ensure this doesn't happen, keep accumulating stats over reset.
1. Remove function calls which reset hardware and netdev statistics.
2. Do not rollover statistics in ice_stat_update40 during reset.

The driver is currently using ICE_LINK_SPEED_* defines that mirror what
ethtool.h defines, with one exception ICE_LINK_SPEED_UNKNOWN.
This issue is fixed by the following changes:
1. replace ICE_LINK_SPEED_UNKNOWN with 0 because SPEED_UNKNOWN in
ethtool.h is "-1" and that doesn't match the driver's expected behavior
2. transform ICE_LINK_SPEED_*MBPS to SPEED_* using static tables and
fls()-1 to convert from BIT() to an index in a table.

Previously, during removal of trusted VF when VF is down there was
number of spurious interrupt equal to number of queues on VF.
Add check if VF already has inactive queues. If VF is disabled and
has inactive rx queues then do not disable rx queues.
Add check in ice_vsi_stop_tx_ring if it's VF's vsi and if VF is
disabled.

There are problems if allocated queues less than Traffic Classes.
Commit a632b2a4c920 ("ice: ethtool: Prohibit improper channel config
for DCB") already disallow setting less queues than TCs.
Another case is if we first set less queues, and later update more TCs
config due to LLDP, ice_vsi_cfg_tc() will failed but left dirty
num_txq/rxq and tc_cfg in vsi, that will cause invalid pointer access.

Ice driver allocates per cpu XDP queues so that redirect path can safely
use smp_processor_id() as an index to the array. At the same time
though, XDP rings are used to pick NAPI context to call napi_schedule()
or set NAPIF_STATE_MISSED. When user reduces queue count, say to 8, and
num_possible_cpus() of underlying platform is 44, then this means queue
vectors with correlated NAPI contexts will carry several XDP queues.
This in turn can result in a broken behavior where NAPI context of
interest will never be scheduled and AF_XDP socket will not process any
traffic.
To fix this, let us change the way how XDP rings are assigned to Rx
rings and use this information later on when setting
ice_tx_ring::xsk_pool pointer. For each Rx ring, grab the associated
queue vector and walk through Tx ring's linked list. Once we stumble
upon XDP ring in it, assign this ring to ice_rx_ring::xdp_ring.
Previous [0] approach of fixing this issue was for txonly scenario
because of the described grouping of XDP rings across queue vectors. So,
relying on Rx ring meant that NAPI context could be scheduled with a
queue vector without XDP ring with associated XSK pool.

The driver can allow the user to configure whether the CRC aka the FCS
(Frame Check Sequence) is DMA'd to the host as part of the receive
buffer. The driver usually wants this feature disabled so that the
hardware checks the FCS and strips it in order to save PCI bandwidth.
Control the reception of FCS to the host using the command:
ethtool -K eth0 rx-fcs <on|off>
The default shown in ethtool -k eth0 | grep fcs; should be "off", as the
hardware will drop any frame with a bad checksum, and DMA of the
checksum is useless overhead especially for small packets.
Testing Hints:
test the FCS/CRC arrives with received packets using
tcpdump -nnpi eth0 -xxxx
and it should show crc data as the last 4 bytes of the packet. Can also
use wireshark to turn on CRC checking and check the data is correct.

When at least two interfaces are bonded and a bridge is enabled on the
bond, an error can occur when the bridge is removed and re-added. The
reason for the error is because promiscuous mode was not fully cleared from
the VLAN VSI in the hardware. With this change, promiscuous mode is
properly removed when the bridge disconnects from bonding.

In current implementation default VSI switch filter is only able to
forward traffic to a single VSI. This limits promiscuous mode with
private flag 'vf-true-promisc-support' to a single VF. Enabling it on
the second VF won't work. Also allmulticast support doesn't seem to be
properly implemented when vf-true-promisc-support is true.
Use standard ice_add_rule_internal() function that already implements
forwarding to multiple VSI's instead of constructing AQ call manually.
Add switch filter for allmulticast mode when vf-true-promisc-support is
enabled. The same filter is added regardless of the flag - it doesn't
matter for this case.
Remove unnecessary fields in switch structure. From now on book keeping
will be done by ice_add_rule_internal().
Refactor unnecessarily passed function arguments.
To test:
1) Create 2 VM's, and two VF's. Attach VF's to VM's.
2) Enable promiscuous mode on both of them and check if
traffic is seen on both of them.

Do not allow setting less channels, than Traffic Classes there are
via ethtool. There must be at least one channel per Traffic Class.
If you set less channels, than Traffic Classes there are, then during
ice_vsi_rebuild there would be allocated only the requested amount
of tx/rx rings in ice_vsi_alloc_arrays. But later in ice_vsi_setup_q_map
there would be requested at least one channel per Traffic Class. This
results in setting num_rxq > alloc_rxq and num_txq > alloc_txq.
Later, there would be a NULL pointer dereference in
ice_vsi_map_rings_to_vectors, because we go beyond of rx_rings or
tx_rings arrays.
Change ice_set_channels() to return error if you try to allocate less
channels, than Traffic Classes there are.
Change ice_vsi_setup_q_map() and ice_vsi_setup_q_map_mqprio() to return
status code instead of void.
Add error handling for ice_vsi_setup_q_map() and
ice_vsi_setup_q_map_mqprio() in ice_vsi_init() and ice_vsi_cfg_tc().

In switchdev mode VF VLAN caps will not be set there is no need
to have specific VLAN ops for representor that only returns not
supported error.
As VLAN configuration commands will be blocked, the VF driver
can't disable VLAN stripping at initialization. It leads to the
situation when VLAN stripping on VF VSI is on, but in kernel it
is off. To prevent this, disable VLAN stripping in VSI
initialization. It doesn't break other usecases, because it is set
according to kernel settings.

Adaptive-rx and Adaptive-tx are interrupt moderation settings
that can be enabled/disabled using ethtool:
ethtool -C ethX adaptive-rx on/off adaptive-tx on/off
Unfortunately those settings are getting cleared after
changing number of queues, or in ethtool world 'channels':
ethtool -L ethX rx 1 tx 1
Clearing was happening due to introduction of bit fields
in ice_ring_container struct. This way only itr_setting
bits were rebuilt during ice_vsi_rebuild_set_coalesce().
Introduce an anonymous struct of bitfields and create a
union to refer to them as a single variable.
This way variable can be easily saved and restored.
