True, some devices take 802.3 frames and do the translation and
everything themselves. I dunno. I guess it would make sense to make it
mac80211 anyway because ieee80211 doesn't care and the other drivers are
probably handling this in some other way anyway (if maybe even by using
different dma descriptors, or just not caring because transfer speeds
are low enough)
