/*
* The NetBSD ieee80211_radiotap man page
* (http://netbsd.gw.com/cgi-bin/man-cgi?ieee80211_radiotap+9+NetBSD-current)
* says:
*
* Radiotap capture fields must be naturally aligned. That is, 16-, 32-,
* and 64-bit fields must begin on 16-, 32-, and 64-bit boundaries, respec-
* tively. In this way, drivers can avoid unaligned accesses to radiotap
* capture fields. radiotap-compliant drivers must insert padding before a
* capture field to ensure its natural alignment. radiotap-compliant packet
* dissectors, such as tcpdump(8), expect the padding.

*
* As used, this field conflates channel properties (which
* need not be stored per packet but are more or less fixed)
* with packet properties (like the modulation).
*
* The channel field, in practice, seems to be used, in some
* cases, to indicate channel properties (from which the packet
* modulation cannot be inferred) and, in other cases, to
* indicate the packet's modulation.
*
* There is even a capture in which the channel field indicates
* that the channel is an OFDM channel with a center frequency
* of 2452 MHz, and the data rate field indicates a 1 Mb/s rate,
* which means you can't rely on the CCK/OFDM/dynamic CCK/OFDM
* bits in the channel field to indicate anything. (There are
* also captures in which a 1 Mb/s packet has the CCK flag set,
* so it clearly doesn't indicate how the packet was transmitted.)
*
* That makes the channel field unusable either for determining
* the channel type or for determining the packet modulation,
* as it cannot be determined how it's being used. The xchannel
* field might well be used inconsistently as well.
*
* Fortunately, there are other ways to determine the packet
* modulation:
*
* if there's an FHSS flag, the packet was transmitted
* using the 802.11 legacy FHSS modulation;
*
* otherwise:
*
* if there's an HE field, the packet was transmitted
* using one of the 11ax HE PHY's specified modulations;
*
* otherwise, if there's a VHT field, the packet was
* transmitted using one of the 11ac VHT PHY's specified
* modulations;
*
* otherwise, if there's an MCS field, the packet was
* transmitted using one of the 11n HT PHY's specified
* modulations;
*
* otherwise:
*
* if the data rate is 1 Mb/s or 2 Mb/s, the packet was
* transmitted using the 802.11 legacy DSSS modulation
* (we ignore the IR PHY - was it ever implemented?);
*
* if the data rate is 5 Mb/s or 11 Mb/s, the packet
* was transmitted using the 802.11b DSSS/CCK modulation
* (or the now-obsolete DSSS/PBCC modulation; *if* we can
* rely on the channel/xchannel field's "CCK channel" and
* "Dynamic CCK-OFDM channel" flags, the absence of either
* flag would presumably indicate DSSS/PBCC);
*
* if the data rate is 22 Mb/s or 33 Mb/s, the packet was
* transmitted using the 802.11b DSSS/PBCC modulation (as
* those speeds aren't supported by DSSS/CCK);
*
* if the data rate is one of the OFDM rates for the 11a
* OFDM PHY and the OFDM part of the 11g ERP PHY, the
* packet was transmitted with the 11g/11a OFDM modulation.
*
* We've already handled the HE, VHT, and MCS fields, and may
* have attempted to use the channel and xchannel fields to
* guess the modulation. That guess might get the wrong answer
* for 11g "Dynamic CCK-OFDM" channels.
*
* If we have the data rate, we use it to:
*
* fix up the 11g channels;
*
* determine the modulation if we haven't been able to
* determine it any other way.
