mac80211: notify driver on subsequent CSA beacons

2019-02-22T12:45:51+00:00

Some drivers may want to track further the CSA beacons, for example
to compensate for buggy APs that change the beacon count or quiet
mode during CSA flow.

mac80211: abort CSA if beacon does not include CSA IEs

2019-02-22T12:43:53+00:00

In case we receive a beacon without CSA IE while we are in
the middle of channel switch - abort the operation.

mac80211: support max channel switch time element

2019-02-22T12:42:54+00:00

2018 REVmd of the spec introduces the max channel switch time
element which is optionally included in beacons/probes when there
is a channel switch / extended channel switch element.
The value represents the maximum delay between the time the AP
transmitted the last beacon in current channel and the expected
time of the first beacon in the new channel, in TU.

Parse the value and pass it to the driver.

mac80211: indicate support for multiple BSSID

mac80211: support multi-bssid

2019-02-08T12:56:37+00:00

Add support for multi-bssid.

This includes:
- Parsing multi-bssid element
- Overriding DTIM values
- Taking into account in various places the inner BSSID instead of
  transmitter BSSID
- Save aside some multi-bssid properties needed by drivers

mac80211: fix missing/malformed documentation

2019-02-01T11:11:13+00:00

Fix the missing and malformed documentation that kernel-doc and
sphinx warn about. While at it, also add some things to the docs
to fix missing links.

Sadly, the only way I could find to fix this was to add some
trailing whitespace.

mac80211: Fix documentation strings for airtime-related variables

2019-02-01T10:04:53+00:00

There was a typo in the documentation for weight_multiplier in mac80211.h,
and the doc was missing entirely for airtime and airtime_weight in sta_info.h.

mac80211: Expose ieee80211_schedule_txq() function

2019-01-25T13:05:27+00:00

Since we reworked ieee80211_return_txq() so it assumes that the caller
takes care of logging, we need another function that can be called without
holding any locks. Introduce ieee80211_schedule_txq() which serves this
purpose.

mac80211: minstrel_ht: add flag to indicate missing/inaccurate tx A-MPDU length

2019-01-19T08:56:56+00:00

Some hardware (e.g. MediaTek MT7603) cannot report A-MPDU length in tx status
information. Add support for a flag to indicate that, to allow minstrel_ht
to use a fixed value in its internal calculation (which gives better results
than just defaulting to 1).

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.
