## 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

expected\_throughput

expected throughput in kbps (including 802.11 headers) towards this station.

## DESCRIPTION

Station information filled by driver for **get\_station** and dump\_station.
