wifi: wfx: implement wfx_remain_on_channel() With some conditions, the device is able to send/receive frames during scan operation. So, it is possible to use it implement the "remain on channel" feature. We just ask for a passive scan (without sending any probe request) on one channel. This architecture allows to leverage some interesting features: - if the device is AP, the device switches channel just after the next beacon and the beacons are stopped during the off-channel interval. - if the device is connected, it advertises it is asleep before to switch channel (so the AP should stop to try to send data) Signed-off-by: Jérôme Pouiller <jerome.pouiller@silabs.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20231004172843.195332-9-jerome.pouiller@silabs.com

wifi: wfx: scan_lock is global to the device Currently, one scan_lock is associated to each vif. However, concurrent scan on vifs is explicitly prohibited by the device. Currently, scan_lock is associated with a vif but it is always locked with conf_mutex (there is a case where conf_mutex is not associated to scan_lock but scan_lock is tested on all interfaces). So concurrent scan on vifs cannot happen. So, this patch relocate scan_lock to the device and simplify the code.

wfx: use container_of() to get vif Currently, upon virtual interface creation, wfx_add_interface() stores a reference to the corresponding struct ieee80211_vif in private data, for later usage. This is not needed when using the container_of construct. This construct already has all the info it needs to retrieve the reference to the corresponding struct from the offset that is already available, inherent in container_of(), between its type and member inputs (struct ieee80211_vif and drv_priv, respectively). Remove vif (which was previously storing the reference to the struct ieee80211_vif) from the struct wfx_vif, define a function wvif_to_vif(wvif) for container_of(), and replace all wvif->vif with the newly defined container_of construct.
