The fix in [0] introduces issue with mt7921 chips (at least), due to the 802.11 encapsulation offloading support of those chips. ieee80211_tx_h_select_key() treated 802.3 frames as if they were 802.11 ones causing the skb's control block hw_key to be invalid. The first patch fixes the root cause of this issue and the second one reapplies the initial use after free fix that has been temporarly reverted meanwhile.
