Is there any chance this might be applicable to the 802.11 layer as
well? We will definitely still need an ndo_select_queue handler to reset
in the case where the peer doesn't support QoS, but it seems the part
that depends on the frame itself could be pushed out to the generic
framework instead of having net/wireless/util.c:cfg80211_classify8021d?
