Assuming sched_scan_stop operation is synchronous the driver may not necessary call ieee80211_sched_scan_stopped_work. Since this work is the only place where sched_scan_sdata is released we can possibly run into situation when it is never released. Fix this by releasing it just after calling drv_sched_scan_stop.

commit de74a1d9 "mac80211: fix WPA with VLAN on AP side with ps-sta" fixed an issue where queued multicast packets would be sent out encrypted with the key of an other bss. commit "7cbf9d01" "mac80211: fix oops on mesh PS broadcast forwarding" essentially reverted it, because vif.type cannot be AP_VLAN due to the check to vif.type in ieee80211_get_buffered_bc before. As the later commit intended to fix the MESH case, fix it by checking for IFTYPE_AP instead of IFTYPE_AP_VLAN.

Since Stanislaw's patch removing the quiescing code, mac80211 had a race regarding suspend vs. authentication: as cfg80211 doesn't track authentication attempts, it can't abort them. Therefore the attempts may be kept running while suspending, which can lead to all kinds of issues, in at least some cases causing an error in iwlmvm firmware. Fix this by aborting the authentication attempt when suspending.

When still authenticating the mac80211 code handling a deauthentication requests from userspace doesn't verify that the request is valid in any way, fix that. Additionally, it never returns an error, even if there's no connection or authentication attempt, fix that as well. While at it, move the message to not print a message in the error case and to distinguish between the two cases. Also simplify the code by duplicating the cfg80211 call.

In certain situations we want to trigger reprocessing of the last regulatory hint. One situation in which this makes sense is the case where the cfg80211 was built-in to the kernel, CFG80211_INTERNAL_REGDB was not enabled and the CRDA binary is on a partition not availble during early boot. In such a case we want to be able to re-process the same request at some other point. When we are asked to re-process the same request we need to be careful to not kfree it, addresses that.

Commit "nl80211: send event when AP operation is stopped" added an event to notify user space that an AP interface has been stopped, to handle cases such as suspend etc. The event is sent regardless if the stop AP flow was triggered by user space or due to internal state change. This might cause issues with wpa_supplicant/hostapd flows that consider stop AP flow as a synchronous one, e.g., AP/GO channel change in the absence of CSA support. In such cases, the flow will restart the AP immediately after the stop AP flow is done, and only handle the stop AP event after the current flow is done, and as a result stop the AP again. Change the current implementation to only send the event in case the stop AP was triggered due to an internal reason.

Introduce NL80211_RRF_AUTO_BW rule flag. If this flag set maximum available bandwidth should be calculated base on contiguous rules and wider channels will be allowed to cross multiple contiguous/overlapping frequency ranges. In case of old kernels maximum bandwidth from regulatory rule will be used, while there is no NL80211_RRF_AUTO_BW flag. This fixes the previous commit 97524820 ("cfg80211: regulatory introduce maximum bandwidth calculation") which was found to be a problem for userspace API compatibility.

While framing the TDLS Setup Confirmation frame, the driver needs to know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the VHT/HT operation / WMM parameter elements accordingly. Supplicant determines if the TDLS peer is VHT/HT/WMM capable based on the presence of the respective IEs in the received TDLS Setup Response frame. The host driver should not need to parse the received TDLS Response frame and thus, should be able to rely on the supplicant to indicate the capability of the peer through additional flags while transmitting the TDLS Setup Confirmation frame through tdls_mgmt operations.
