4377 * The comment in the radiotap.org page about the suggested
4378 * xchannel field says:
4379 *
4380 * As used, this field conflates channel properties (which
4381 * need not be stored per packet but are more or less fixed)
4382 * with packet properties (like the modulation).
4383 *
4384 * The channel field, in practice, seems to be used, in some
4385 * cases, to indicate channel properties (from which the packet
4386 * modulation cannot be inferred) and, in other cases, to
4387 * indicate the packet's modulation.
4388 *
4389 * There is even a capture in which the channel field indicates
4390 * that the channel is an OFDM channel with a center frequency
4391 * of 2452 MHz, and the data rate field indicates a 1 Mb/s rate,
4392 * which means you can't rely on the CCK/OFDM/dynamic CCK/OFDM
4393 * bits in the channel field to indicate anything. (There are
4394 * also captures in which a 1 Mb/s packet has the CCK flag set,
4395 * so it clearly doesn't indicate how the packet was transmitted.)
4396 *
4397 * That makes the channel field unusable either for determining
4398 * the channel type or for determining the packet modulation,
4399 * as it cannot be determined how it's being used. The xchannel
4400 * field might well be used inconsistently as well.
4401 *
4402 * Fortunately, there are other ways to determine the packet
4403 * modulation:
4404 *
4405 * if there's an FHSS flag, the packet was transmitted
4406 * using the 802.11 legacy FHSS modulation;
4407 *
4408 * otherwise:
4409 *
4410 * if there's an HE field, the packet was transmitted
4411 * using one of the 11ax HE PHY's specified modulations;
4412 *
4413 * otherwise, if there's a VHT field, the packet was
4414 * transmitted using one of the 11ac VHT PHY's specified
4415 * modulations;
4416 *
4417 * otherwise, if there's an MCS field, the packet was
4418 * transmitted using one of the 11n HT PHY's specified
4419 * modulations;
4420 *
4421 * otherwise:
4422 *
4423 * if the data rate is 1 Mb/s or 2 Mb/s, the packet was
4424 * transmitted using the 802.11 legacy DSSS modulation
4425 * (we ignore the IR PHY - was it ever implemented?);
4426 *
4427 * if the data rate is 5 Mb/s or 11 Mb/s, the packet
4428 * was transmitted using the 802.11b DSSS/CCK modulation
4429 * (or the now-obsolete DSSS/PBCC modulation; *if* we can
4430 * rely on the channel/xchannel field's "CCK channel" and
4431 * "Dynamic CCK-OFDM channel" flags, the absence of either
4432 * flag would presumably indicate DSSS/PBCC);
4433 *
4434 * if the data rate is 22 Mb/s or 33 Mb/s, the packet was
4435 * transmitted using the 802.11b DSSS/PBCC modulation (as
4436 * those speeds aren't supported by DSSS/CCK);
4437 *
4438 * if the data rate is one of the OFDM rates for the 11a
4439 * OFDM PHY and the OFDM part of the 11g ERP PHY, the
4440 * packet was transmitted with the 11g/11a OFDM modulation.
4441 *
4442 * We've already handled the HE, VHT, and MCS fields, and may
4443 * have attempted to use the channel and xchannel fields to
4444 * guess the modulation. That guess might get the wrong answer
4445 * for 11g "Dynamic CCK-OFDM" channels.
4446 *
4447 * If we have the data rate, we use it to:
4448 *
4449 * fix up the 11g channels;
4450 *
4451 * determine the modulation if we haven't been able to
