However, it really all depends on the hardware too ... Maybe we should
put more of the logic into drivers, and have mac80211 only export its
required headroom?
Or maybe we should just not bother with having drivers do the alignment
any more -- mac80211 does that now and it only does it if necessary
(i.e. not on powerpc/x86)
