VSI, especially VF could request to add or remove filter for another VSI,
driver should really guide such request and disallow it.
However, instead of returning error for such malicious request, driver
can simply return success.
In addition, we are not tracking number of MAC filters configured per
VF correctly - and this leads to issue updating VF MAC filters whenever
they were removed and re-configured via bringing VF interface down and
up. Also, since VF could send request to update multiple MAC filters at
once, driver should program those filters individually in the switch, in
order to determine which action resulted to error, and communicate
accordingly to the VF.
So, with this changes, we now track number of filters added right from
when VF resources allocation is done, and could properly add filters for
both trusted and non_trusted VFs, without MAC filters mis-match issue in
the switch...
Also refactor code, so that driver can use new function to add or remove
MAC filters.

Users expect ethtool statistics to be updated on-demand when invoking
'ethtool -S <iface>' instead of providing a snapshot of statistics taken
once a second (the frequency of the watchdog task where stats are currently
updated). Update stats every time 'ethtool -S <iface>' is run.
Also, fix an indentation style issue and an unnecessary local variable

The virtchnl interface provides a mechanism for a VF driver to request
head writeback support. This feature is deprecated as of AVF 1.0, but
older versions of a VF driver may still attempt to request the mode.
Since the ice hardware does not support head writeback, we should not
accept Tx queue configuration which attempts to enable it.
Currently, the driver simply assumes that the headwb_enabled bit will
never be set.
If a VF driver does request head writeback, the configuration will
return successfully, even though head writeback is not enabled. This
leaves the VF driver in a non functional state since it is assuming to
be operating in head writeback mode.
Fix the PF driver to reject any attempt to setup headwb_enabled.

Currently, only the DCBx status is taken into account to
determine if FW LLDP is possible. But there are NVM version
coming out with DCBx enabled, and FW LLDP disabled. This
is causing errors where the driver sees that DCBx is not
disabled, and then tries to register for LLDP MIB change
events, and fails.

For control packets (i.e. LLDP packets) to be able to egress
from the main VSI, a bit has to be set in the TX_descriptor.
This should only be done for the main VSI and only if the
FW LLDP agent is disabled. A bit to allow this also has to
be set in the VSI context.
Add the logic to add the necessary bits in the VSI context
for the PF_VSI and the TX_descriptors for control packets
egressing the PF_VSI.

Driver waits after issuing a reset. When a reset takes too long a driver
gives up. Implemented by invoking PF reset in a loop. After defined
number of unsuccessful PF reset trials it returns error.
Without this patch PF reset fails when NIC is in recovery mode.
So make i40e_set_mac_type() public. i40e driver requires i40e_set_mac_type()
to be public. It is required for recovery mode handling. Without this patch

The functions i40e_aq_get_phy_abilities_resp() and i40e_set_fc() both
have giant structure on the stack, which makes each one use stack frames
larger than 500 bytes.
As clang decides one function into the other, we get a warning for
exceeding the frame size limit on 32-bit architectures:
drivers/net/ethernet/intel/i40e/i40e_common.c:1654:23: error: stack frame size of 1116 bytes in function 'i40e_set_fc' [-Werror,-Wframe-larger-than=]
When building with gcc, the inlining does not happen, but i40e_set_fc()
calls i40e_aq_get_phy_abilities_resp() anyway, so they add up on the
kernel stack just as much.
The parts that actually use large stacks don't overlap, so make sure
each one is a separate function, and mark them as noinline_for_stack to
prevent the compilers from combining them again.

Currently we use the ICE_MBXQ_LEN for both the Mailbox send and receive
queues that are used to communicate with VFs. This is fine for the send
queue because the PF driver will lock the queue for every single send,
but for the Mailbox receive queue every VF is posting to its Mailbox
send queue and the hardware is then handing the message to the PF on its
Mailbox receive queue. This becomes a problem with many VFs because it
seems to overburden the Mailbox receive queue on the PF. Fix this by
increasing the Mailbox receive queue for the PF to 512 entries.
The number 512 was determined based on the number of VFs supported by
the device. We can have a total of 256 VFs so in the worst case this
allows the VFs to put 2 messages in the PFs Mailbox receive queue at the
same time.

Currently there are a couple places where the VF is waiting too long when

spin for longer than necessary in the __IAVF_STARTUP state. Sometimes
it causes the AVF to go into the __IAVF_COMM_FAILED, which may retrigger
the __IAVF_STARTUP state. Try to reduce the chance of this happening by

This patch restructures how VFs are configured, and resources allocated.
Instead of freeing resources that were never allocated, and resetting
empty VFs that have never been created - the new flow will just allocate
resources for number of requested VFs based on the availability.
During VFs initialization process, global interrupt is disabled, and
rearmed after getting MSIX vectors for VFs. This allows immediate mailbox
communications, instead of delaying it till later and VFs.
PF communications resulted to using polling instead of actual interrupt.
The issue manifested when creating higher number of VFs (128 VFs) per PF.

====================
40GbE Intel Wired LAN Driver Updates 2019-08-05
This series contains updates to i40e driver only.
Dmitrii adds missing statistic counters for VEB and VEB TC's.
Slawomir adds support for logging the "Disable Firmware LLDP" flag
option and its current status.
Jake fixes an issue where VF's being notified of their link status
before their queues are enabled which was causing issues. So always
report link status down when the VF queues are not enabled. Also adds
future proofing when statistics are added or removed by adding checks to
ensure the data pointer for the strings lines up with the expected
statistics count.
Czeslaw fixes the advertised mode reported in ethtool for FEC, where the
"None BaseR RS" was always being displayed no matter what the mode it
was in. Also added logging information when the PF is entering or
leaving "allmulti" (or promiscuous) mode. Fixed up the logging logic
for VF's when leaving multicast mode to not include unicast as well.
v2: drop Aleksandr's patch (previously patch #2 in the series) to
display the VF MAC address that is set by the VF while community
feedback is addressed.
