The mcs field indicates the MCS rate index as in IEEE_802.11n-2009
The known field indicates which information is known:
flag |
definition |
0x01 |
bandwidth |
0x02 |
MCS index known (in mcs part of the field) |
0x04 |
guard interval |
0x08 |
HT format |
0x10 |
FEC type |
0xe0 |
reserved |
The flags field is any combination of the following:
flag |
definition |
0x03 |
bandwidth - 0: 20, 1: 40, 2: 20L, 3: 20U |
0x04 |
guard interval - 0: long GI, 1: short GI |
0x08 |
HT format - 0: mixed, 1: greenfield |
0x10 |
FEC type - 0: BCC, 1: LDPC |
0xe0 |
