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.
