I don't think IEEE80211_TX_QUEUE_AFTER_BEACON was originally used for
anything inside the d80211 code so it was just a queue identifier that
was shared between the hardware driver and more generic 802.11 code. As
such, it should be fine to do this inside the hardware drivers and
remove this from mac80211.

This was originally used only for setting up queue parameters for Beacon
frames in IBSS and that can be done differently.

Sure, that should be removed.
