2024-06-26wifi: mac80211: inform the low level if drv_stop() is a suspendEmmanuel Grumbach1-1/+1
This will allow the low level driver to take different actions for different flows.

2024-02-08wifi: mac80211: simplify non-chanctx driversJohannes Berg1-0/+4
There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.

mac80211 is fully switching over to the internal TX queue (iTXQ) implementation. Update all drivers not yet providing the now mandatory wake_tx_queue() callback. As an side effect the netdev interfaces of all updated drivers will switch to the noqueue qdisc.

We'll use bss_conf for per-link configuration later, so move out all the non-link-specific data out into a new struct ieee80211_vif_cfg used in the vif.
