CCK not sure, OFDM and HT yes. And at wide range of distances. (Tx
rates usually hit mcs 12 to 14 with 2s ht20 ap)

I have looked into stuff I was able to dig out from other src codes,
ie protection, ifs, nav, bk slot. (Because I do not have datasheet,
every thing is based on my guesses.) One thing I could not figure out
is if on-chip memory is properly allocated for rx pkt. (It seems
memory can be allocated for different things, ie beacon, enc keys).
