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.

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.

Merge tag 'staging-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging driver updates from Greg KH: "Here is the big set of staging driver updates for 5.19-rc1. Lots of forward progress happened this development cycle, one driver (wfx wireless driver) got merged into the real portion of the kernel, and another one (unisys) was removed as no one is around anymore to take care of it and no one has the hardware. Combined with loads of tiny driver cleanups overall we removed 13k lines of code from the tree, a nice improvement. Other than the wfx and unisys driver changes the major points of this merge is: - r8188eu driver cleanups. So many cleanups. It's amazing just how many things have been cleaned up here, and yet, how many remain to go. Lots of work happened here, and it doesn't look to slow down any time soon. - other wifi driver cleanups. Not as many as the r8188eu driver, but still pretty impressive from a janitorial point of view. - bcm2853 driver cleanups - other very minor driver cleanups All of these have been in the linux-next tree for weeks with no reported issues" * tag 'staging-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (363 commits) staging: r8188eu: remove include/rtw_debug.h staging: r8188eu: prevent ->Ssid overflow in rtw_wx_set_scan() staging: r8188eu: delete rtw_wx_read/write32() staging: r8188eu: Remove multiple assignments staging: r8188eu: add check for kzalloc staging: r8188eu: fix warnings in rtw_wlan_util staging: r8188eu: fix warnings in rtw_pwrctrl staging: r8188eu: fix warnings in rtw_p2p staging: rtl8712: fix uninit-value in r871xu_drv_init() staging: rtl8712: fix uninit-value in usb_read8() and friends staging: rtl8712: add error handler in r8712_usbctrl_vendorreq() staging: r8188eu: remove _drv_ defines from include/rtw_debug.h staging: vc04_services: remove unused macro staging: rtl8192u: remove null check after call container_of() staging: rtl8192e: remove null check after call container_of() staging: ks7010: remove null check after call container_of() staging: r8188eu: remove HW_VAR_AC_PARAM_BE from SetHwReg8188EU() staging: r8188eu: assoc_rsp and assoc_rsp_len are not used staging: r8188eu: last_rx_mgnt_pkts is set but not used staging: r8188eu: simplify error handling in recv_func_prehandle ...
