This series is a first attempt at porting the Airtime Queue Limits concept from
the out-of-tree ath10k implementation[0] to mac80211. This version takes Kan's
patch to do the throttling in mac80211, and replaces the driver API with the
mechanism from the previous version of my series, which instead calculated the
expected airtime at dequeue time inside mac80211, storing it in the SKB cb
field.

This series also imports Felix' airtime calculation code from mt76 into
mac80211, adjusting the API so it can be used from TX dequeue, by extracting the
latest TX rate from the tx_stats structure kept for each station.

As before, I've only compile tested this (lacking the proper hardware to do more
testing). So I'm hoping someone with a proper testing setup can take the whole
thing for a spin... :)

The series is also available in my git repo here:
https://git.kernel.org/pub/scm/linux/kernel/git/toke/linux.git/log/?h=mac80211-aql-02

Changelog:

v4:
  - Fix calculation that clamps the maximum airtime to fit into 10 bits
  - Incorporate Rich Brown's nits for the commit message in Kan's patch
  - Add fewer local variables to ieee80211_tx_dequeue()
v3:
  - Move the tx_time_est field so it's shared with ack_frame_id, and use units
    of 4us for the value stored in it.
  - Move the addition of the Ethernet header size into ieee80211_calc_expected_tx_airtime()
v2:
  - Integrate Kan's approach to airtime throttling.
  - Hopefully fix the cb struct alignment on big-endian architectures.
