Instead of relying on rps_needed, it is safer to use a separate
static key, since we do not want to enable TCP rx_skb_cache
by default. This feature can cause huge increase of memory

This patch makes it possible to log only AQ descriptors, without the
entire AQ message buffers being dumped too. It should greatly reduce
kernel log size in cases where a full AQ dump is not needed.
Selection is made by setting flags in hw->debug_mask.

This patch fixes the problem with a kernel panic occurring when trying
to bind the i40e driver to a non-i40e port. The problem is fixed by
checking if the BAR size in the device is large enough by reading the
highest register.

This patch lets untrusted VF to create up to 16 VLANs.
It was implemented by increasing I40E_VC_MAX_VLAN_PER_VF up to 16.
Without this patch untrusted VF could create only up to 8 VLANs.

The counter variable in i40e_clean_tx_irq starts out negative and climbs
to 0. So it should not be defined as a u16. This was working by accident
due to the fact the u16 overflows and underflows predictably.
Replace the u16 with int, which is signed and can handle the negati
