mac80211: Add airtime accounting and scheduling to TXQs

2019-01-19T08:31:43+00:00

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
(through ieee80211_next_txq()) in a way that enforces airtime fairness
between active stations. This scheduling works the same way as the ath9k
in-driver airtime fairness scheduling. If no airtime usage is reported
by the driver, the scheduler will default to round-robin scheduling.

For drivers that don't control TXQ scheduling in software, a new API
function, ieee80211_txq_may_transmit(), is added which the driver can use
to check if the TXQ is eligible for transmission, or should be throttled to
enforce fairness. Calls to this function must also be enclosed in
ieee80211_txq_schedule_{start,end}() calls to ensure proper locking.

The API ieee80211_txq_may_transmit() also ensures that TXQ list will be
aligned aginst driver's own round-robin scheduler list. i.e it rotates
the TXQ list till it makes the requested node becomes the first entry
in TXQ list. Thus both the TXQ list and driver's list are in sync.

mac80211: debugfs: avoid variable shadowing

2018-11-09T10:14:51+00:00

We have a macro here that uses an inner variable 'i' that
also exists in the outer scope - use '_i' in the macro.

mac80211: add an optional TXQ for other PS-buffered frames

2018-09-05T08:03:13+00:00

Some drivers may want to also use the TXQ abstraction with
non-data packets that need powersave buffering, so add a
hardware flag to allow this.

mac80211: Dynamically set CoDel parameters per station

2017-05-17T14:03:40+00:00

CoDel can be too aggressive if a station sends at a very low rate,
leading reduced throughput. This gets worse the more stations are
present, as each station gets more bursty the longer the round-robin
scheduling between stations takes.

This adds dynamic adjustment of CoDel parameters per station. It uses
the rate selection information to estimate throughput and sets more
lenient CoDel parameters if the estimated throughput is below a
threshold (modified by the number of active stations).

A new callback is added that drivers can use to notify mac80211 about
changes in expected throughput, so the same adjustment can be made for
cards that implement rate control in firmware. Drivers that don't use
this will just get the default parameters.

mac80211: add back lost debugfs files

Somehow these files were never present or lost, but the code
is there and they seem somewhat useful, so add them back.
