MEMBERS
       filled
           bitflag of flags using the bits of enum nl80211_sta_info to indicate the relevant
           values in this struct for them

       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 (size of MPDUs) received from this station

       tx_bytes
           bytes (size of MPDUs) 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 (MSDUs & MMPDUs) received from this station

       tx_packets
           packets (MSDUs & MMPDUs) transmitted to this station

       tx_retries
           cumulative retry counts (MPDUs)

       tx_failed
           number of failed transmissions (MPDUs) (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.

       rx_beacon
           number of beacons received from this peer

       rx_duration
           aggregate PPDU duration(usecs) for all the frames from a peer

       rx_beacon_signal_avg
           signal strength average (in dBm) for beacons received from this peer

       pertid[IEEE80211_NUM_TIDS + 1]
           per-TID statistics, see struct cfg80211_tid_stats, using the last (IEEE80211_NUM_TIDS)
           index for MSDUs not encapsulated in QoS-MPDUs.

DESCRIPTION
       Station information filled by driver for get_station and dump_station.
