MEMBERS

filled

bitflag of flags from enum station_info_flags

connected_time

time(in secs) since a station is last connected

inactive_time

time since last station activity (tx/rx) in milliseconds

rx_bytes

bytes received from this station

tx_bytes

bytes transmitted to this station

llid

mesh local link id

plid

mesh peer link id

plink_state

mesh peer link state

signal

The signal strength, type depends on the wiphy's signal_type. For CFG80211_SIGNAL_TYPE_MBM, value is expressed in _dBm_.

signal_avg

Average signal strength, type depends on the wiphy's signal_type. For CFG80211_SIGNAL_TYPE_MBM, value is expressed in _dBm_.

chains

bitmask for filled values in chain_signal, chain_signal_avg

chain_signal[IEEE80211_MAX_CHAINS]

per-chain signal strength of last received packet in dBm

chain_signal_avg[IEEE80211_MAX_CHAINS]

per-chain signal strength average in dBm

txrate

current unicast bitrate from this station

rxrate

current unicast bitrate to this station

rx_packets

packets received from this station

tx_packets

packets transmitted to this station

tx_retries

cumulative retry counts

tx_failed

number of failed transmissions (retries exceeded, no ACK)

rx_dropped_misc

Dropped for un-specified reason.

bss_param

current BSS parameters

sta_flags

station flags mask & values

generation

generation number for nl80211 dumps. This number should increase every time the list of stations changes, i.e. when a station is added or removed, so that userspace can tell whether it got a consistent snapshot.

assoc_req_ies

IEs from (Re)Association Request. This is used only when in AP mode with drivers that do not use user space MLME/SME implementation. The information is provided for the cfg80211_new_sta calls to notify user space of the IEs.

assoc_req_ies_len

Length of assoc_req_ies buffer in octets.

beacon_loss_count

Number of times beacon loss event has triggered.

t_offset

Time offset of the station relative to this host.

local_pm

local mesh STA power save mode

peer_pm

peer mesh STA power save mode

nonpeer_pm

non-peer mesh STA power save mode

DESCRIPTION

Station information filled by driver for get_station and dump_station.
