o replace out-of-line copy of FCS w/ a flag that indicates the

Browse Source 
frame includes FCS (requires applications to be updated, but since
  we weren't doing the out-of-line FCS stuff anyway app changes
  were needed already)
o add a flag to indicate padding exists between the 802.11 header and
  the payload (e.g. for Atheros cards)
o diff reducation against netbsd
