On 32-bit platforms packet counters are stored in a net_device_stats struct
as unsigned long integers. As a result, after some time of network activity
an overflow takes place in network packet counters. This patch makes use of
new structs for holding interface statistics.

Hardware encryption seems to break encrypted unicast mgmt tx.
Unfortunately the hardware TXWI header does not have a bit to indicate
that a frame is software encrypted, so sw-encrypted frames need to use a
different WCID. For that to work, the CCMP PN needs to be generated in
software, which makes things a bit slower, so only do it for keys that
also need to tx management frames.

Fix hw queue configuration since mt76x2 devices use a reverse queue
enumeration respect to mac80211 one:
 - 0: AC_BE
 - 1: AC_BK
 - 2: AC_VI

The issue can be reproduced sending two concurrent flow using
two separate queues:
 - VO: 20Mbps UDP traffic
 - BE: TCP traffic

In this scenario the UDP traffic will be blocked by the TCP one.
Fix it configuring properly WMM hw queue parameters

Aquantia atlantic driver new devices support

This patchset introduces a support for new Aquantia hardware:
AQC11x family with updated hardware (B1) and firmware (2.x and 3.x branches).

For that, a number of improvements in overall driver model were done:
 - Firmware specific ops tables. Firmware 2.x and 3.x series support
   functions are now in separate fw2x module.
 - PCI module cleanup and simplification done.
 - Verified and tested hardware reset process.
