When roaming / suspending, it makes no sense to wait until the transmit queues of the device are empty. In extreme condition they can be starved (VO saturating the air), but even in regular cases, it is pointless to delay the roaming because the low level driver is trying to send packets to an AP which is far away. We'd rather drop these packets and let TCP retransmit if needed. This will allow to speed up the roaming. For suspend, the explanation is even more trivial.

Implement the cfg80211 TDLS channel switch ops and introduce new mac80211 ones for low-level drivers. Verify low-level driver support for the new ops when using the relevant wiphy feature bit. Also verify the peer supports channel switching before passing the command down. Add a new STA flag to track the off-channel state with the TDLS peer and make sure to cancel the channel-switch if the peer STA is unexpectedly removed.

We currently track the QoS capability twice: for all peer stations in the WLAN_STA_WME flag, and for any clients associated to an AP interface separately for drivers in the sta->sta.wme field. Remove the WLAN_STA_WME flag and track the capability only in the driver-visible field, getting rid of the limitation that the field is only valid in AP mode.

Since the teardown packet is created while the queues are stopped, it isn't sent immediately, but rather is pending. To be sure that when we flush the queues prior to destroying the station we also send this packet - the tasklet handling pending packets is invoked to flush the packets.

Infer the TDLS initiator and track it in mac80211 via a STA flag. This avoids breaking old userspace that doesn't pass it via nl80211 APIs. The only case where userspace will need to pass the initiator is when the STA is removed due to unreachability before a teardown packet is sent. Support for unreachability was only recently added to wpa_supplicant, so it won't be a problem in practice.

As the spec mandates, flush data in the AP path before transmitting the first setup frame. Data packets transmitted during setup are already dropped in the Tx path. For the teardown flow, flush all packets in the direct path before transmitting the teardown frame. Un-authorize the peer sta after teardown is sent, forcing all subsequent Tx to the peer through the AP. Make sure to flush the queues when disabling the link to get the teardown packet out.
