Those are a couple of fixes that prevent crashes due to processing
packets (especially multicast ones) for TX after vif is stopped (either
after a mesh interface left the group or interface is put down).
The first one ensure the key info passed to drivers through ieee80211
skb control block is up to date, even after key removal.
The second one ensure no packets get processed after vif driver private
data is cleared in ieee80211_do_stop().
v2:
- Add Fixes tag
- Clear SKB's control block key before in ieee80211_tx_dequeue()
instead of ieee80211_tx_h_select_key()
- Add wireless tag and fix type in subject
- Because subject changed, v1 can be found at
