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
MFC after: 1 week
here but it includes completed 802.11g, WPA, 802.11i, 802.1x, WME/WMM,
AP-side power-save, crypto plugin framework, authenticator plugin framework,
and access control plugin frameowrk.
o #ifdef _KERNEL the fallback definition for DLT_IEEE802_11_RADIO
o fix many comments
o rename antenna stuff and fix units/reference signal
o change IEEE80211_RADIOTAP_DBM_TX_POWER from unsigned 16-bit value
to a signed 8-bit value
o change IEEE80211_RADIOTAP_FLAGS from 16 bits to 8 bits to simplify
padding requirements
o drop IEEE80211_RADIOTAP_TIME
o change IEEE80211_RADIOTAP_ANTENNA from 16 bits to 8 bits
o drop IEEE80211_RADIOTAP_PAD
o add channel flag definitions for outside the kernel so radiotap
doesn't depend on stuff in ieee80211*.h
