PHY metadata for 802.11ac (VHT) captures.
| uint8_t ieee_802_11ac::bandwidth |
Channel bandwidth in MHz (e.g. 20, 40, 80, 160).
| unsigned ieee_802_11ac::beamformed |
True if the frame was transmitted using beamforming.
| uint8_t ieee_802_11ac::fec |
Per-user FEC type bitmask: bit set = LDPC, bit clear = BCC, for up to 4 MU-MIMO users.
| uint8_t ieee_802_11ac::group_id |
VHT group ID identifying the MU-MIMO group for this transmission.
| unsigned ieee_802_11ac::has_bandwidth |
Non-zero if bandwidth contains a valid value.
| unsigned ieee_802_11ac::has_beamformed |
Non-zero if beamformed contains a valid value.
| unsigned ieee_802_11ac::has_fec |
Non-zero if fec contains a valid value.
| unsigned ieee_802_11ac::has_group_id |
Non-zero if group_id contains a valid value.
| unsigned ieee_802_11ac::has_ldpc_extra_ofdm_symbol |
Non-zero if ldpc_extra_ofdm_symbol contains a valid value.
| unsigned ieee_802_11ac::has_partial_aid |
Non-zero if partial_aid contains a valid value.
| unsigned ieee_802_11ac::has_short_gi |
Non-zero if short_gi contains a valid value.
| unsigned ieee_802_11ac::has_short_gi_nsym_disambig |
Non-zero if short_gi_nsym_disambig contains a valid value.
| unsigned ieee_802_11ac::has_stbc |
Non-zero if stbc contains a valid value.
| unsigned ieee_802_11ac::has_txop_ps_not_allowed |
Non-zero if txop_ps_not_allowed contains a valid value.
| unsigned ieee_802_11ac::ldpc_extra_ofdm_symbol |
True if an extra OFDM symbol was appended to support LDPC encoding.
| uint8_t ieee_802_11ac::mcs[4] |
MCS index per user for up to 4 MU-MIMO users.
| uint8_t ieee_802_11ac::nss[4] |
Number of spatial streams per user for up to 4 MU-MIMO users.
| uint16_t ieee_802_11ac::partial_aid |
Partial AID (Association ID) used to identify the recipient in MU-MIMO transmissions.
| unsigned ieee_802_11ac::short_gi |
True if a short guard interval (400 ns) was used; false for long guard interval (800 ns).
| unsigned ieee_802_11ac::short_gi_nsym_disambig |
True if the short GI Nsym disambiguation bit is set, indicating an extra symbol was added.
| unsigned ieee_802_11ac::stbc |
True if all spatial streams were transmitted with Space-Time Block Coding (STBC).
| unsigned ieee_802_11ac::txop_ps_not_allowed |
True if the TXOP Power Save mode is not permitted for this transmission.
