wiphy_apply_custom_regulatory() implies WIPHY_FLAG_CUSTOM_REGULATORY but we never enforced it, do that now and warn if the driver didn't set it. All drivers should be following this today already. Having WIPHY_FLAG_CUSTOM_REGULATORY does not however mean you will use wiphy_apply_custom_regulatory() though, you may have your own _orig value set up tools / helpers. The intel drivers are examples of this type of driver. Signed-off-by: Luis R. Rodriguez <mcgrof@do-not-panic.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Currently, frames that go into the reordering buffer are stored at index ieee80211_sn_sub(sn, tid_rx->ssn) % tid_rx->buf_size. The offset calculation to the starting sequence number (SSN) is useless and just adds overhead so simply use sn % tid_rx->buf_size. This means the reordering buffer will start to be filled somewhere in the middle (at SSN % buf_size) and continue to get used from there, but there's no reason to start from the beginning.

These two flags are used for the same purpose, just combine them into a no-ir flag to annotate no initiating radiation is allowed. Old userspace sending either flag will have it treated as the no-ir flag. To be considerate to older userspace we also send both the no-ir flag and the old no-ibss flags. Newer userspace will have to be aware of older kernels.

When we disassociate, mac80211 removes the station and then, it sets the bss it unsets the assoc bool in bss_info. Since the firwmware wants it the opposite (first set the MAC context as unassoc, and only then, remove the STA of the API), we have a small period of time in which the STA in firmware doesn't have a valid ieee80211_sta pointer. During that time, iwl_mvm_vif->ap_sta_id, is still set to the STA in firmware that represent the AP.

Implement the required procedures for mesh channel switching as defined in the IEEE Std 802.11-2012 section 10.9.8.4.3 and also handle the CSA and MCSP elements as followed: * Add the function for updating the beacon and probe response frames with CSA and MCSP elements during the period of switching to the new channel. Both CSA and MCSP elements must be included in beacon and probe response frames until the intended channel switch time. * The ifmsh->csa_settings is set to NULL and the CSA and MCSP elements will then be removed from the beacon or probe response frames once the new channel is switched to.

Allow the triggering of CSA frame using mesh interface. The rules are more or less same with IBSS, such as not allowed to change between the band and channel width has to be same from the previous mode. Also, move the ieee80211_send_action_csa to a common space so that it can be re-used by mesh interface.

Process the CSA frame according to the procedures define in IEEE Std 802.11-2012 section 10.9.8.4.3 as follow: * The mesh channel switch parameters element (MCSP) must be availabe. * If the MCSP's TTL is 1, drop the frame but still process the CSA. * If the MCSP's precedence value is less than or equal to the current precedence value, drop the frame and do not process the CSA. * The CSA frame is forwarded after TTL is decremented by 1 and the initiator field is set to 0. Transmit restrict field and others are maintained as is. * No beacon or probe response frame are handled here. Also, introduce the debug message used for mesh CSA purpose.

This patch fixes errors in the mesh powersave logic which cause that remote peers do not get peer power mode change notifications and mesh peer service periods (MPSPs) got stuck. When closing a peer link, set the (now invalid) peer-specific power mode to 'unknown'. Avoid overhead when local power mode is unchanged. Reliably clear MPSP flags on peering status update. Avoid MPSP flags getting stuck by not requesting a further MPSP ownership if we already are an MPSP owner.
