mac80211: fix station rate table updates on assoc

2021-02-01T14:07:09Z

If the driver uses .sta_add, station entries are only uploaded after the sta is in assoc state. Fix early station rate table updates by deferring them until the sta has been uploaded.

mac80211: don't warn about CW params when not using them

2019-07-20T19:40:32Z

ieee80211_set_wmm_default() normally sets up the initial CW min/max for each queue, except that it skips doing this if the driver doesn't support ->conf_tx. We still end up calling drv_conf_tx() in some cases (e.g., ieee80211_reconfig()), which also still won't do anything useful...except it complains here about the invalid CW parameters. Let's just skip the WARN if we weren't going to do anything useful with the parameters.

mac80211: store tx power value from user to station

2019-04-26T11:02:11Z

This patch introduce a new driver callback drv_sta_set_txpwr. This API will copy the transmit power value passed from user space and call the driver callback to set the tx power for the station.

mac80211: add offset_tsf driver op and use it for mesh

2016-09-30T11:45:44Z

This allows the mesh sync (and debugfs) code to make incremental TSF adjustments, avoiding any uncertainty introduced by delay in programming absolute TSF. Signed-off-by: Thomas Pedersen Signed-off-by: Johannes Berg

mac80211: refactor monitor representation in sdata

2016-09-12T09:24:47Z

Insert the u32 monitor flags variable in a new structure that represents a monitor interface. This will allow to add more configuration variables to that structure which will happen in an upcoming change. Signed-off-by: Aviya Erenfeld Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

mac80211: pass block ack session timeout to to driver

2016-01-14T10:13:17Z

Currently mac80211 does not inform the driver of the session block ack timeout when starting a rx aggregation session. Drivers that manage the reorder buffer need to know this parameter. Seeing that there are now too many arguments for the drv_ampdu_action() function, wrap them inside a structure. Signed-off-by: Sara Sharon Signed-off-by: Johannes Berg

mac80211: call drv_stop only if driver is started

2015-11-03T09:41:12Z

If drv_start() fails during hw_restart, all the running interfaces are being closed/stopped, which results in drv_stop() being called, although the driver was never started successfully. This might cause drivers to perform operations on uninitialized memory (as they assume it was initialized on drv_start) Consider the local->started flag, and call the driver's stop() op only if drv_start() succeeded before. Move drv_start() and drv_stop() to driver-ops.c, as they are no longer simple wrappers. Signed-off-by: Eliad Peller Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg
