+Subject: [PATCH] mac80211: swap NEED_TXPROCESSING and HW_80211_ENCAP tx
+ flags
+
+In order to unify the tx status path, the hw 802.11 encapsulation flag
+needs to survive the trip to the tx status call.
+Since we don't have any free bits in info->flags, we need to move one.
+IEEE80211_TX_INTFL_NEED_TXPROCESSING is only used internally in mac80211,
+and only before the call into the driver.
+
+Signed-off-by: Felix Fietkau <nbd@nbd.name>
