mac80211: propagate the support for TWT to the driver

2018-12-18T13:18:49+00:00

TWT is a feature that was added in 11ah and enhanced in
11ax. There are two bits that need to be set if we want
to use the feature in 11ax: one in the HE Capability IE
and one in the Extended Capability IE. This is because
of backward compatibility between 11ah and 11ax.

In order to simplify the flow for the low level driver
in managed mode, aggregate the two bits and add a boolean
that tells whether TWT is supported or not, but only if
11ax is supported.

mac80211: document RCU requirements for ieee80211_tx_dequeue()

2018-12-18T12:18:30+00:00

In the iwlwifi conversion, we sometimes call this from outside
of the wake_tx_queue() method, and in those cases must be in an
RCU critical section. Document this requirement.

mac80211: allow hardware scan to fall back to software

2018-11-09T10:37:04+00:00

In some cases, like in the rsi driver hardware scan offload, there
may be scenarios in which hardware scan might not be available or
desirable.

Allow drivers to cope with this by letting them fall back to software
scan by returning the special value 1 from the hardware scan method.

mac80211: allow drivers to use peer measurement API

2018-11-09T10:20:34+00:00

There's nothing much for mac80211 to do, so only pass through
the requests with minimal checks and tracing. The driver must
call cfg80211's results APIs.

mac80211: implement ieee80211_tx_rate_update to update rate

2018-10-12T11:05:40+00:00

Current mac80211 has provision to update tx status through
ieee80211_tx_status() and ieee80211_tx_status_ext(). But
drivers like ath10k updates the tx status from the skb except
txrate, txrate will be updated from a different path, peer stats.

Using ieee80211_tx_status_ext() in two different paths
(one for the stats, one for the tx rate) would duplicate
the stats instead.

To avoid this stats duplication, ieee80211_tx_rate_update()
is implemented.

mac80211: support FTM responder configuration/statistics

2018-10-12T10:46:09+00:00

New bss param ftm_responder is used to notify the driver to
enable fine timing request (FTM) responder role in AP mode.

Plumb the new cfg80211 API for FTM responder statistics through to
the driver API in mac80211.

mac80211: add an option for drivers to check if packets can be aggregated

2018-09-05T08:11:50+00:00

Some hardwares have limitations on the packets' type in AMSDU.
Add an optional driver callback to determine if two skbs can
be used in the same AMSDU or not.

mac80211: allow AMSDU size limitation per-TID

Some drivers may have AMSDU size limitation per TID, due to
HW constrains. Add an option to set this limit.

mac80211: add an option for station management TXQ

2018-09-05T08:10:11+00:00

We have a TXQ abstraction for non-data packets that need
powersave buffering. Since the AP cannot sleep, in case
of station we can use this TXQ for all management frames,
regardless if they are bufferable. Add HW flag to allow
that.
