Subject: [PATCH] mac80211: don't put null-data frames on the normal TXQ
Git-commit: 0832b603c7583e75f149ea984827b6d929f336b5
Patch-mainline: v4.19-rc1
References: FATE#326294
Since (QoS) NDP frames shouldn't be put into aggregation nor are
assigned real sequence numbers, etc. it's better to treat them as
non-data packets and not put them on the normal TXQs, for example
when building A-MPDUs they need to be treated specially, and they
are more used for management (e.g. to see if the station is alive)
anyway.
