Enumeration Type Documentation

enum ieee80211_sta_info_flags

enum ieee80211_sta_info_flags - Stations flags

These flags are used with &struct sta_info's member, but only indirectly with set_sta_flag() and friends.

: Station is authenticated. : Station is associated. : Station is in power-save mode : Station is authorized to send/receive traffic. This bit is always checked so needs to be enabled for all stations when virtual port control is not in use. : Station is capable of receiving short-preamble frames. : We're associated to that station, it is an AP. : Station is a QoS-STA. : Station is one of our WDS peers. : Clear PS filter in hardware (using the IEEE80211_TX_CTL_CLEAR_PS_FILT control flag) when the next frame to this station is transmitted. : Management frame protection is used with this STA. : Used to deny ADDBA requests (both TX and RX) during suspend/resume and station removal. : driver requires keeping this station in power-save mode logically to flush frames that might still be in the queues : Station sent PS-poll while driver was keeping station in power-save mode, reply when the driver unblocks. : Station is a TDLS peer. : This TDLS peer is authorized to send direct packets. This means the link is enabled. : Station requested unscheduled SP while driver was keeping station in power-save mode, reply when the driver unblocks the station. : Station is in a service period, so don't try to reply to other uAPSD trigger frames or PS-Poll.
