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. Signed-off-by: Johannes Berg

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. Reported-by: kbuild test robot Signed-off-by: Toke Høiland-Jørgensen Signed-off-by: Johannes Berg

mac80211: mesh: use average bitrate for link metric calculation

2019-01-19T08:55:54+00:00

Use bitrate moving average to smooth out link metric and stablize path selection. Signed-off-by: Julan Hsu Signed-off-by: Johannes Berg

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.

{nl,mac}80211: report gate connectivity in station info

2018-11-09T10:38:29+00:00

Capture the current state of gate connectivity from the mesh formation field in mesh config whenever we receive a beacon, and report that via GET_STATION. This allows applications doing mesh peering in userspace to make peering decisions based on peers' current upstream connectivity. Signed-off-by: Bob Copeland Signed-off-by: Johannes Berg

mac80211: add support for HE

2018-06-18T20:40:32+00:00

mac80211: allocate and fill tidstats only when needed

2018-05-18T09:40:44+00:00

This fixes memory leaks in the case where we just have the station info on the stack for internal usage without sending it to cfg80211. Fixes: 8689c051a201 ("cfg80211: dynamically allocate per-tid stats for station info") Signed-off-by: Johannes Berg

mac80211: average ack rssi support for data frames

2018-05-07T19:41:16+00:00

The driver will process the RSSI if available and send it to mac80211. mac80211 will compute the weighted average of ack RSSI for stations. Signed-off-by: Balaji Pothunoori Signed-off-by: Johannes Berg

mac80211: Add tx ack signal support in sta info

2018-02-19T12:22:28+00:00

This allows users to get ack signal strength of last transmitted frame. Signed-off-by: Venkateswara Naralasetty Signed-off-by: Johannes Berg

mac80211: aggregation: Convert timers to use timer_setup()

2017-11-20T15:55:23+00:00

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. This removes the tid mapping array and expands the tid structures to add a pointer back to the station, along with the tid index itself. Cc: Johannes Berg Cc: "David S.
