net80211 and PPI header

1. Not only one RSSI but for every antenna (also in dBm)
2. HT greenfield/HT mixed indicator
4. Number of spatial streams (STBC)
3. A-MPDU support (MPDU density, A-MPDU reassembly)

The most important one is A-MPDU support, i think.

Wireshark supports PPI header and can handle A-MPDUs very nicely.

That's it for now :-)
