====================
mlxsw qdisc refactoring
This patchset refactors the qdisc handling in mlxsw driver in order to make
it more object oriented like.
It helps readability, laying the groundwork for the offloading of
additional qdiscs by the driver
This patchset also makes the qdiscs statistics more generic.
Patch 1 moves the qdiscs declaration to the spectrum_qdisc.c
Patches 2-3 clean the offloaded stats requests. Patch 2 changes the RED
generic stats struct to be sharable by other offloaded qdiscs. Patch 3
changes the xstats request to be like the stats. Note that these patches
are outside the driver scope.
Patches 4-5 clean the statistics related functions and structs within the
driver.
Patches 6-7 decrease the need for the same parameters to be sent to many
functions.
Patches 8-11 create a functions pointers struct, to make the qdiscs
handling more object oriented like.

If a qdisc is being replaced by another qdisc of the same type, it can
simply override over its configuration.
However, if it replaces a qdisc of another type, it needs to be removed
before setting the new qdisc.

Create a generic qdisc replace function.
For that goal, add three functions to the qdisc ops struct:
* check_params: Checks if the given parameters are offloadable.
* replace: Offload the given parameters.
* clean_stats: clean the qdisc stats for the offloaded qdisc.
integrate RED offloading into using the new internal replace API.

Every qdisc op gets the qdisc handle ID as well as its location. Each one
of them, beside replace, checks if the handle doesn't match the qdisc in
the given location, and if so, it returns without running the actual op.
Unite these checks to one comparison function and avoid sending the handle
id to these ops.

Function ipv6_push_rthdr4 allows to add an IPv6 Segment Routing Header
to a socket through setsockopt, but the current implementation doesn't
copy possible TLVs at the end of the SRH received from userspace.
Therefore, the execution of the following branch if (sr_has_hmac(sr_phdr))
{ ... } will never complete since the len and type fields of a possible
HMAC TLV are not copied, hence seg6_get_tlv_hmac will return an error,
and the HMAC will not be computed.
This commit adds a memcpy in case TLVs have been appended to the SRH.

The link state and exception interrupts may be masked when we probe.
The firmware should in theory prevent sending (and automasking) those
interrupts if the device is disabled, but if my reading of the FW code
is correct there are firmwares out there with race conditions in this
area. The interrupt may also be masked if previous driver which used
the device was malfunctioning and we didn't load the FW (there is no
other good way to comprehensively reset the PF).
Note that FW unmasks the data interrupts by itself when vNIC is
enabled, such helpful operation is not performed for LSC/EXN interrupts.
Always unmask the auxiliary interrupts after request_irq(). On the
remove path add missing PCI write flush before free_irq().

Having the interrupts firing while we are polling causes extra overhead and
isn't needed for most systems out there. If an interrupt is lost us
experiencing a 2s latency spike before recovering is still not acceptable
and masks the issue. We are better off just identifying systems that lose
interrupts and instead enable workarounds for those systems.
To that end I am dropping the code that was strobing the interrupts as
there is a narrow window where having them enabled can actually cause
race issues anyway where a few stray packets might get misses if the
interrupt is re-enabled and fires before we call napi_complete.

We introduced the virtchnl interface in order to have an interface for
talking to a virtual device driver which was host-driver agnostic. This
interface has its own definitions, including one for link speed.
The host driver has to talk to the virtchnl interface using these new
definitions in order to remain compatible. Today, the i40e link_speed
enumerations are value-exact matches for the virtchnl interface, so it
was originally decided to simply use a typecast.
However, this is unsafe, and makes it easier for future drivers to
continue this unsafe practice. There is nothing guaranteeing these
values are exact, and the type-cast would hide any compiler warning
which indicates the problem.
Rather than rely on this type cast, introduce a helper function which
can convert the AdminQ link speed definition into a virtchnl
definition. This can then be used by host driver implementations in
order to safely convert to the interface recognized by the virtual
functions.
If the link speed is not able to be represented by the virtchnl
definitions we'll report UNKNOWN which is the safest result.
This will ensure that should the driver specific link_speeds actual bit
definitions change, we do not report them incorrectly according to the
VF.
Additionally, this provides a better pattern for future drivers to copy,
as it is more likely a future device may not use the exact same bit-wise
definition as the current virtchnl interface.

We currently notify a VF of the link state after ENABLE_QUEUES, which is
the last thing a VF does after being configured. Guests may not actually
ENABLE_QUEUES until they get configured, and thus between driver load
and device configuration the VF may show inaccurate link status.
Fix this by also sending the link state after GET_VF_RESOURCES. Although
we could remove the message following ENABLE_QUEUES, it's not that
significant of a loss, so this patch just keeps both to ensure maximum
compatibility with guests on various OSes.
Specifically, without this patch guests running FreeBSD will display
inaccurate link state until the device is brought up. This is mostly
a cosmetic issue but can be confusing to system administrators.

If i40evf_open() is called quickly at the same time as a reset occurs
(such as via ethtool) it is possible for the device to attempt to open
while a reset is in progress. This occurs because the driver was not
holding the critical task bit lock during i40evf_open, nor was it
holding it around the call to i40evf_up_complete() in
i40evf_reset_task().
We didn't hold the lock previously because calls to i40evf_down() would
take the bit lock directly, and this would have caused a deadlock.
To avoid this, we'll move the bit lock handling out of i40evf_down() and
into the callers of this function. Additionally, we'll now hold the bit
lock over the entire set of steps when going up or down, to ensure that
we remain consistent.
Ultimately this causes us to serialize the transitions between down and
up properly, and avoid changing status while we're resetting.

Stop overloading the __I40EVF_IN_CRITICAL_TASK bit lock to protect the
mac_filter_list and vlan_filter_list. Instead, implement a spinlock to
protect these two lists, similar to how we protect the hash in the i40e
PF code.
Ensure that every place where we access the list uses the spinlock to
ensure consistency, and stop holding the critical section around blocks
of code which only need access to the macvlan filter lists.
This refactor helps simplify the locking behavior, and is necessary as
a future refactor to the __I40EVF_IN_CRITICAL_TASK would cause
a deadlock otherwise.

In i40evf_reset_task we use netif_running() to determine whether or not
the device is currently up. This allows us to properly free queue memory
and shut down things before we request the hardware reset.
It turns out that we cannot be guaranteed of netif_running() returning
false until the device is fully up, as the kernel core code sets
__LINK_STATE_START prior to calling .ndo_open. Since we're not holding
the rtnl_lock(), it's possible that the driver's i40evf_open handler
function is currently being called while we're resetting.
We can't simply hold the rtnl_lock() while checking netif_running() as
this could cause a deadlock with the i40evf_open() function.
Additionally, we can't avoid the deadlock by holding the rtnl_lock()
over the whole reset path, as this essentially serializes all resets,
and can cause massive delays if we have multiple VFs on a system.
Instead, lets just check our own internal state __I40EVF_RUNNING state
field. This allows us to ensure that the state is correct and is only
set after we've finished bringing the device up.
Without this change we might free data structures about device queues
and other memory before they've been fully allocated.

net: create dynamic software irq moderation library
This converts the dynamic interrupt moderation library from the mlx5e
driver into a library so it can be used by any driver. The penultimate
patch in this set adds support for this new dynamic interrupt moderation
library in the bnxt_en driver and the last patch creates an entry in the
MAINTAINERS file for this library.
The main purpose of this code is to allow an administrator to make sure
that default coalesce settings are optimized for low latency, but
quickly adapt to handle high throughput/bulk traffic by altering how
much time passes before popping an interrupt.
For any new driver the following changes would be needed to use this
library:
- add elements in ring struct to track items needed by this library
- create function that can be called to actually set coalesce settings
for the driver
