preprocessor macros.

s/IEEE80211_RADIOTAP_F_FCS/IEEE80211_RADIOTAP_F_BADFCS/.

9ff230d3d6 Define four new radiotap fields per discussions with John Bicket, Sam 
Leffler, and others:

        IEEE80211_RADIOTAP_RX_FLAGS = 14,
        IEEE80211_RADIOTAP_TX_FLAGS = 15,
        IEEE80211_RADIOTAP_RTS_RETRIES = 16,
        IEEE80211_RADIOTAP_DATA_RETRIES = 17,

I describe the fields in the manual page and in comments in the
header file (cross-referenced by the manual page).

f5e353f96f Add a hint to the compiler that the radiotap header requires 8-byte 
alignment.  This

        1 helps GCC make better code for architectures such as ARM
          where it would otherwise do a lot of byte-loads and shifts
          to load a multi-byte word, and

        2 ensures that the compiler will add no padding between a
          radiotap header and a 64-bit or narrower field that
          follows it.

c205496a96 Note in radiotap header file and manual page that radiotap fields 
are little-endian.  Fix wi(4) and atw(4) to reflect this fact.

few days ago.

da04ad7825 Add flag IEEE80211_RADIOTAP_F_BADFCS for packets whose checksum 
doesn't match their contents.  While I'm here, remove the mention
of field IEEE80211_RADIOTAP_FCS, which wasn't adopted.

9063402978 Resolve conflicts in importation of 18-May-2005 ath(4) / net80211(9) 
from FreeBSD.  Introduce compatibility shims (sys/dev/ic/ath_netbsd.[ch],
sys/net80211/ieee80211_netbsd.[ch]).  Update drivers (an, atu, atw,
awi, ipw, iwi, rtw, wi) for the new net80211(9) API.

5c35c045ac Sync with FreeBSD. Some apps get confused when the FCS comes at 
the end of the tapped frame, so stick it into the radiotap header.

f37c61d56c Add missing flags IEEE80211_CHAN_DYN and IEEE80211_CHAN_GFSK, needed 
by userland programs to interpret radiotap channel indications.

9270de9dc4 Updates to 802.11 radiotap. The _DB_ flags were used everywhere to 
denote a signed dBm Rx power, so rename them to _DBM_ and change
the signedness.  Add new _DB_ flags for unsigned Rx power measured
from an arbitrary reference.

Try to synchronize net80211/ieee80211_radiotap.h with my tcpdump
sources (which public tcpdump has not seen, yet) and with FreeBSD.

23d8f48692 Add data-link type DLT_IEEE802_11_RADIO to wi and atw. DLT_IEEE802_11_RADIO 
lets you monitor radio stats like received signal strength, which
diversity antenna was used, channel/frequency, modulation, and data
rate.
