}

The radio metadata header of the received packet, which is the common header at the beginning of all RX callback buffers in promiscuous mode.

Fields

rssi: i32

Received Signal Strength Indicator (RSSI) of the packet, in dBm.

rate: u32

PHY rate encoding of the packet. Only valid for non-HT (802.11b/g) packets.

sig_mode: u32

Protocol of the received packet: 0 for non-HT (11bg), 1 for HT (11n), 3 for VHT (11ac).

mcs: u32

Modulation and Coding Scheme (MCS). Indicates modulation for HT (11n) packets.

cwb: u32

Channel bandwidth of the packet: 0 for 20MHz, 1 for 40MHz.

smoothing: u32

Channel estimate smoothing: 1 recommends smoothing; 0 recommends per-carrier-independent estimate.

not_sounding: u32

Sounding indicator: 0 for sounding PPDU (used for channel estimation); 1 for non-sounding PPDU.

aggregation: u32

Aggregation status: 0 for MPDU packet, 1 for AMPDU packet.

stbc: u32

Space-Time Block Coding (STBC) status: 0 for non-STBC packet, 1 for STBC packet.

fec_coding: u32

Forward Error Correction (FEC) status: indicates if LDPC coding is used for 11n packets.

sgi: u32

Short Guard Interval (SGI): 0 for long guard interval, 1 for short guard interval.

ampdu_cnt: u32

Number of subframes aggregated in an AMPDU packet.

channel: u32

Primary channel on which the packet is received.

secondary_channel: u32

Secondary channel on which the packet is received: 0 for none, 1 for above, 2 for below.

timestamp: u32

Timestamp of when the packet is received, in microseconds. Precise only if modem sleep or light sleep is not enabled.

noise_floor: i32

Noise floor of the Radio Frequency module, in dBm.

ant: u32

Antenna number from which the packet is received: 0 for antenna 0, 1 for antenna 1.

sig_len: u32

Length of the packet including the Frame Check Sequence (FCS).

rx_state: u32

State of the packet: 0 for no error, other values indicate error codes.

Implementations

impl RxControlInfo

pub unsafe fn from_raw(rx_cntl: *const wifi_pkt_rx_ctrl_t) -> Self

Create an instance from a raw pointer to wifi_pkt_rx_ctrl_t.

Safety

When calling this, you must ensure, that rx_cntl points to a valid instance of wifi_pkt_rx_ctrl_t.

Trait Implementations

impl Clone for RxControlInfo

fn clone(&self) -> RxControlInfo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RxControlInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
