linux.git/include/net/mac80211.h, branch v6.9-rc2 Linux kernel source tree wifi: mac80211: introduce a feature flag for quiet in CSA 2024-03-04T13:33:58+00:00 Johannes Berg johannes.berg@intel.com 2024-02-28T08:55:45+00:00 6f0107d195a812074c6f977d492ffc99ba3ff2bb When doing CSA in multi-link, there really isn't a need to stop transmissions entirely. Add a feature flag for drivers to indicate they can handle quiet in CSA (be it by parsing themselves, or by implementing drv_pre_channel_switch()), to make that possible. Also clean up the csa_block_tx handling: it clearly cannot handle multi-link due to the way queues are stopped, move it to the sdata. Drivers should be doing it themselves for working properly during CSA in MLO anyway. Also rename it to indicate that it reflects TX was blocked at mac80211.
