I received few comments, I'll list them here so that I don't forget
them:

o netlink interface might create problems, I'll remove netlink. cfor
  now but will revisit it later
o wl12xx_80211.h is, well, ugly
o fragmentation in the hardware might not be worth the trouble
o "*fc &= ~IEEE80211_FCTL_PROTECTED;" shouldn't be necessary, just set
  the status properly
o get_tsf() doesn't need to be atomic anymore, ad-hoc tsf hack can be
  removed

If anyone has more comments, please send them soon. I'm planning to
prepare a patch for adding wl12xx to wireless-testing next week. Let's
see if John takes it :)
