If hci_dev_open fails we need to ensure that the corresponding mgmt_set_powered command gets an appropriate response. This patch fixes the missing response by adding a new mgmt_set_powered_failed function that's used to indicate a power on failure to mgmt. Since a situation with the device being rfkilled may require special handling in user space the patch uses a new dedicated mgmt status code for this.

When changing the MAC address of a single vif mac80211 will check if the new address fits into the address mask specified by the driver. This only needs to be done when using multiple BSSIDs. Hence, check the new address only against all other vifs. Also fix the MAC address assignment on new interfaces if the user changed the address of a vif such that perm_addr is not covered by addr_mask anymore.

Since Eric's commit efe117ab ("Speedup ieee80211_remove_interfaces") there's a bug in mac80211 when it unregisters with AP_VLAN interfaces up. If the AP_VLAN interface was registered after the AP it belongs to (which is the typical case) and then we get into this code path, unregister_netdevice_many() will crash because it isn't prepared to deal with interfaces being closed in the middle of it. Exactly this happens though, because we iterate the list, find the AP master this AP_VLAN belongs to and dev_close() the dependent VLANs. After this, unregister_netdevice_many() won't pick up the fact that the AP_VLAN is already down and will do it again, causing a crash.

A lot of code in mac80211 assumes that the hw queues are set up correctly for all interfaces (except for monitor) but this isn't true for AP_VLAN interfaces. Fix this by copying the AP master configuration when an AP VLAN is brought up, after this the AP interface can't change its configuration any more and needs to be brought down to change it, which also forces AP_VLAN interfaces down, so just copying in open() is sufficient.

The code I added in "mac80211: don't start new netdev queues if driver stopped" crashes for monitor and AP VLAN interfaces because while they have a netdev, they don't have queues set up by the driver. To fix the crash, exclude these from queue accounting here and just start their netdev queues unconditionally. For monitor, this is the best we can do, as we can redirect frames there to any other interface and don't know which one that will since it can be different for each frame. For AP VLAN interfaces, we can do better later and actually properly track the queue status. Not doing this is really a separate bug though.

Waiting for all subframes of an existing aggregation session to drain before allowing mac80211 to start a new one is fragile and deadlocks caused by this behavior have been observed. Since mac80211 has proper synchronization for aggregation session start/stop handling, a better approach to session handling is to simply allow mac80211 to start a new session at any time. This requires changing the code to discard any packets outside of the BlockAck window in the A-MPDU software retry code. This patch implements the above and also simplifies the code.

In http://lkml.indiana.edu/hypermail/linux/kernel/1305.1/index.html, Geert Uytterhoeven reports a new warning when building 3.10-rc1 in this driver. This is caused by using a "#if" test to see if __LITTLE_ENDIAN is set, which fails for all big-endian systems. Change to "ifdef".
