The driver has a check to ensure that NCSI FW section is updated only
if the current FW version in the card supports it. This FW version check
is done using memcmp() which obviously fails in some cases. Fix this by
breaking up the version string into integer version components and
comparing them.

The driver gets the pf_num for Skyhawk and Lancer using
GET_FUNC_CONFIG FW command. But since that command is not
supported in BEx, we need to get it from some other command.
Otherwise TPE recovery would fail since all NIC PFs would
end up with a func num of 0. There's a pci function number
field in the response of GET_CNTL_ATTRIBUTES command that
can be read to get the same info for BEx adapters.

Although rare, it's possible to hit PCI error early on device
probe, meaning possibly some structs are not entirely initialized,
and some might even be completely uninitialized, leading to NULL
pointer dereference.
The i40e driver currently presents a "bad" behavior if device hits
such early PCI error: firstly, the struct i40e_pf might not be
attached to pci_dev yet, leading to a NULL pointer dereference on
access to pf->state.
Even checking if the struct is NULL and avoiding the access in that
case isn't enough, since the driver cannot recover from PCI error
that early; in our experiments we saw multiple failures on kernel
log, like:
[549.664] i40e 0007:01:00.1: Initial pf_reset failed: -15
[549.664] i40e: probe of 0007:01:00.1 failed with error -15
[...]
[871.644] i40e 0007:01:00.1: The driver for the device stopped because the
device firmware failed to init. Try updating your NVM image.
[871.644] i40e: probe of 0007:01:00.1 failed with error -32
[...]
[872.516] i40e 0007:01:00.0: ARQ: Unknown event 0x0000 ignored
Between the first probe failure (error -15) and the second (error -32)
another PCI error happened due to the first bad probe. Also, driver
started to flood console with those ARQ event messages.
This patch will prevent these issues by allowing error recovery
mechanism to remove the failed device from the system instead of
trying to recover from early PCI errors during device probe.

40GbE Intel Wired LAN Driver Updates 2016-10-03
This series contains fixes to i40e only.
Stefan Assmann provides the changes in this series to resolve an issue
where when we run out of MSIx vectors, iWARP gets disabled automatically.
First adds a check for "no vectors left" during MSIx vector allocation
for VMDq, which will prevent more vectors being allocated than available.
Then fixed the MSIx vector redistribution when we reach the hardware limit
for vectors so that additional features like VMDq, iWARP, etc do not get
starved for vectors because the PF is hogging all the resources. Lastly,
fix the issue for flow director by moving the check for the reaching the
vector limit earlier in the code so that a decision can be made on
disabling flow director.

- Convert custom lists to the new infrastructure. The block-mq custom

The driver allocates 1 vector per CPU thread and the current hardware
limit for vectors is 129 per PF. On systems with 128 or more threads
this currently means all vectors are used by the PF leaving no room for
additional features like VMDq, iWARP, etc...
The code that should redistribute the vectors in this case is broken and
never triggers. Fixed the code so that it actually triggers if the
hardware limit is reached and adjust the number of queue pairs
accordingly.
Also the number of initially requested iWARP vectors was not properly
saved when the vector limit was reached, and therefore always zero.
Comparison with debug statement.

i40e 0000:2d:00.0: VMDq disabled, not enough MSI-X vectors
i40e 0000:2d:00.0: IWARP disabled, not enough MSI-X vectors
