If the tx queue is drained during channel change, internal reset and etc, the last descriptor may not be the holding descriptor and we fail to reclaim them. This results in the following two issues. 1. Tx stuck - We drop all the frames coming from upper layer due to shortage in tx desc. 2. Crash - If we fail to reclaim a tx descriptor, we miss to update the tx BA window with the seq number of the frame associated to that desc, which, at some point, result in the following crash due to an assert failure in ath_tx_addto_baw().

The issue is the top level menu does not include a dependency on WLAN_80211 so within the tree structure, Atheros is at the same level as WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with all subsequent drives, so it is really a subordinate.
