+Subject: [PATCH] mac80211: allocate TXQs for active monitor interfaces
+
+Monitor mode interfaces with the active flag are passed down to the driver.
+Drivers using TXQ expect that all interfaces have allocated TXQs before
+they get added.
+
+Fixes: 79af1f866193d ("mac80211: avoid allocating TXQs that won't be used")
