From cc20ff2c6b5d3e28747c6d30ecd097ea1a4d2502 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 8 Sep 2020 14:36:57 +0200 Subject: 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.
