   3 Subject: [PATCH] mac80211: allocate TXQs for active monitor interfaces
   4
   5 Monitor mode interfaces with the active flag are passed down to the driver.
   6 Drivers using TXQ expect that all interfaces have allocated TXQs before
   7 they get added.

   9 Fixes: 79af1f866193d ("mac80211: avoid allocating TXQs that won't be used")
