495 * 2.4 GHz HT40 channels 1 (5), 2 (6), 3 (7), 4 (8), 5 (9), 6 (10), 7 (11)
497 * The channel listed is the center of the lower 20 MHz half of the channel.
498 * The overall center frequency is actually 2 channels (10 MHz) above that,
499 * and the upper half of each HT40 channel is centered 4 channels (20 MHz) away
500 * from the lower half; e.g. the upper half of HT40 channel 1 is channel 5,
501 * and the overall HT40 channel width centers on channel 3.
503 * NOTE: The RXON command uses 20 MHz channel numbers to specify the
504 * control channel to which to tune. RXON also specifies whether the
505 * control channel is the upper or lower half of a HT40 channel.
507 * NOTE: 4965 does not support HT40 channels on 2.4 GHz.
