Bitmap of supported rates (per band)
MAC address
AID we assigned to the station if we're an AP
HT capabilities of this STA; restricted to our own capabilities
VHT capabilities of this STA; restricted to our own capabilities
HE capabilities of this STA
maximal amount of frames in a single AMPDU that this station is allowed to transmit to us. Can be modified by driver.
indicates whether the STA supports QoS/WME (if local devices does, otherwise always false)
bitmap of queues configured for uapsd. Only valid if wme is supported. The bits order is like in IEEE80211_WMM_IE_STA_QOSINFO_AC_*.
max Service Period. Only valid if wme is supported.
in HT/VHT, the maximum number of spatial streams the station can receive at the moment, changed by operating mode notifications and capabilities. The value is only valid after the station moves to associated state.
current bandwidth the station can receive with
current SMPS mode (off, static or dynamic)
rate control selection table
indicates whether the STA is a TDLS peer
indicates the STA is an initiator of the TDLS link. Only valid if the STA is a TDLS peer in the first place.
indicates whether the STA uses management frame protection or not.
indicates the maximal number of MSDUs in a single A-MSDU. Taken from the Extended Capabilities element. 0 means unlimited.
indicates whether the STA supports P2P PS mechanism or not.
Maximum A-MSDU size in bytes recommended by rate control.
Maximum A-MSDU size in bytes for this TID
per-TID data TX queues (if driver uses the TXQ abstraction); note that
the last entry (IEEE80211_NUM_TIDS
) is used for non-data frames
data area for driver use, will always be aligned to sizeof(void \*), size is determined in hw information.
A station table entry represents a station we are possibly
communicating with. Since stations are RCU-managed in
mac80211, any ieee80211_sta pointer you get access to must
either be protected by rcu_read_lock
explicitly or implicitly,
or you must take good care to not use such a pointer after a
call to your sta_remove callback that removed it.
