[otus] enable 802.11n for 2GHz and 5GHz.
This flips on basic 11n for 2GHz/5GHz station operation. * It flips on HT20 and MCS rates; * It enables A-MPDU decap - the payload format is a bit different; * It does do some basic checks for HT40 but I haven't yet flipped on HT40 support; * It enables software A-MSDU transmit; I honestly don't want to make A-MPDU TX work and there are apparently issues with QoS and A-MPDU TX. So I totally am ignoring A-MPDU TX; * MCS rate transmit is fine. I haven't: * A-MPDU TX, as I said above; * made radiotap work fully; * HT40; * short-GI support; * lots of other stuff that honestly no-one is likely to use. But! Hey, this is another ye olde 11n USB NIC that now works pretty OK in 11n rates. A-MPDU receive seems fine enough given it's a draft-n device from before 2010. Tested: * Ye olde UB82 Test NIC (AR9170 + AR9104) - 2GHz/5GHz
