a lot of small fixes and cleanups, the bigger items are:
  * proper mac80211 rate control locking, to fix some random crashes
    (this required changing other locking as well)
  * mac80211 "fast-xmit", a mechanism to reduce, in most cases, the
    amount of code we execute while going from ndo_start_xmit() to
    the driver
  * this also clears the way for properly supporting S/G and checksum
    and segmentation offloads
