Here is the consolidated series of mac80211, ath9k and ath10k changes
for moving TXQ scheduling and airtime fairness into mac80211 and support
airtime fairness.
Three main APIs are defined for TXQ scheduling.
- ieee80211_next_txq
- ieee80211_return_txq
-
From: Toke Høiland-Jørgensen
This moves the ath9k driver to use the mac80211 TXQ scheduling and
airtime accounting APIs, removing the corresponding state tracking
inside the driver.

This adds TX airtime statistics to the cfg80211 station dump (to go along
with the RX info already present), and adds a new parameter to set the
airtime weight of each station. The latter allows userspace to implement
policies for different stations by varying their

This adds airtime accounting and scheduling to the mac80211 TXQ
scheduler. A new callback, ieee80211_sta_register_airtime(), is added
that drivers can call to report airtime usage for stations.
When airtime information is present, mac80211 will schedule TXQs
From: Toke Høiland-Jørgensen
ath10k maintains common txqs list for all stations. This txq
management can be removed by migrating to mac80211 txq APIs
and let mac80211 handle txqs reordering based on reported airtime.
By doing this, txq fairness maintained in ath10k i.e processing

Transmit airtime will be estimated from last tx rate used.
Firmware report tx rate by peer stats. Airtime is computed
on tx path and the same will be reported to mac80211 upon
tx completion.

This adds an API to mac80211 to handle scheduling of TXQs. The interface
between driver and mac80211 for TXQ handling is changed by adding two new
functions: ieee80211_next_txq(), which will return the next TXQ to schedule
in the current round-robin rotation, and

nit: please just indent by a single tab for continuation, trying to line

This comment should have the kernel-doc boilerplate
Also, the names should be NL80211_TID_ATTR_* to disambiguate the
namespace from the top-level NL80211_ATTR_*.

This issue arise in a race condition between ath10k_sta_state() and
ath10k_htt_fetch_peer_stats(), explained in below scenario
Steps:
1. In ath10k_sta_state(), arsta->tx_stats get deallocated before peer deletion
when the station moves from IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST
