Maybe I can do the same for the Linux IEs too, just for reference. We basically enable it only if 802.11a or g is supported (802.11b is not supported), and announce OFDM only rates. The rates are divided by two or four (for 10 and 5 MHz), and rounded up. That's pretty much the only thing which is changed to 20 MHz. BTW, how is HT handled for narrow channels in FreeBSD? Do you just send HT IEs as they are in 20 MHz? Also, do you disable secondary channels? (I would probably do that, using two adjacent 5 MHz channels should be replaceable by one 10 MHz channel ...)
