linux-toradex.git/net/mac80211/trace.h, branch v4.10 Linux kernel for Apalis and Colibri modules mac80211: add offset_tsf driver op and use it for mesh 2016-09-30T11:45:44+00:00 Pedersen, Thomas twp@qca.qualcomm.com 2016-09-28T23:56:28+00:00 354d381baf1126c45d03b5c0d87d22caf938b86b This allows the mesh sync (and debugfs) code to make incremental TSF adjustments, avoiding any uncertainty introduced by delay in programming absolute TSF.

This may cause a situation where a disassociation is handled in control path and results in station removal while there are prior RX frames that were still not processed in other queues. When they will be processed the station will be gone, and the frames will be dropped. Add a synchronization interface to avoid that. When driver returns from the synchronization mac80211 may remove the station.

mac80211: allow the driver to send EOSP when needed 2015-12-04T13:43:32+00:00 Emmanuel Grumbach emmanuel.grumbach@intel.com 2015-11-17T08:24:36+00:00 0ead2510f8cec11ce96308d79a1b4ee272fb5238 This can happen when the driver needs to send less frames than expected and then needs to close the SP. Mac80211 still needs to set the more_data properly based on its buffer state (ps_tx_buffer and buffered frames on other TIDs). To that end, refactor the code that delivers frames upon uAPSD trigger frames to be able to get only the more_data bit without actually delivering those frames in case the driver is just asking to set a NDP with EOSP and MORE_DATA bit properly set.
