24 * enum ieee80211_sta_info_flags - Stations flags
25 *
26 * These flags are used with &struct sta_info's @flags member, but
27 * only indirectly with set_sta_flag() and friends.
28 *
29 * @WLAN_STA_AUTH: Station is authenticated.
30 * @WLAN_STA_ASSOC: Station is associated.
31 * @WLAN_STA_PS_STA: Station is in power-save mode
32 * @WLAN_STA_AUTHORIZED: Station is authorized to send/receive traffic.
33 * This bit is always checked so needs to be enabled for all stations
34 * when virtual port control is not in use.
35 * @WLAN_STA_SHORT_PREAMBLE: Station is capable of receiving short-preamble
36 * frames.
37 * @WLAN_STA_WDS: Station is one of our WDS peers.
38 * @WLAN_STA_CLEAR_PS_FILT: Clear PS filter in hardware (using the
39 * IEEE80211_TX_CTL_CLEAR_PS_FILT control flag) when the next
40 * frame to this station is transmitted.
41 * @WLAN_STA_MFP: Management frame protection is used with this STA.
42 * @WLAN_STA_BLOCK_BA: Used to deny ADDBA requests (both TX and RX)
43 * during suspend/resume and station removal.
44 * @WLAN_STA_PS_DRIVER: driver requires keeping this station in
45 * power-save mode logically to flush frames that might still
46 * be in the queues
47 * @WLAN_STA_PSPOLL: Station sent PS-poll while driver was keeping
48 * station in power-save mode, reply when the driver unblocks.
49 * @WLAN_STA_TDLS_PEER: Station is a TDLS peer.
50 * @WLAN_STA_TDLS_PEER_AUTH: This TDLS peer is authorized to send direct
51 * packets. This means the link is enabled.
52 * @WLAN_STA_TDLS_INITIATOR: We are the initiator of the TDLS link with this
53 * station.
54 * @WLAN_STA_TDLS_CHAN_SWITCH: This TDLS peer supports TDLS channel-switching
55 * @WLAN_STA_TDLS_OFF_CHANNEL: The local STA is currently off-channel with this
56 * TDLS peer
57 * @WLAN_STA_TDLS_WIDER_BW: This TDLS peer supports working on a wider bw on
58 * the BSS base channel.
59 * @WLAN_STA_UAPSD: Station requested unscheduled SP while driver was
60 * keeping station in power-save mode, reply when the driver
61 * unblocks the station.
62 * @WLAN_STA_SP: Station is in a service period, so don't try to
63 * reply to other uAPSD trigger frames or PS-Poll.
64 * @WLAN_STA_4ADDR_EVENT: 4-addr event was already sent for this frame.
65 * @WLAN_STA_INSERTED: This station is inserted into the hash table.
66 * @WLAN_STA_RATE_CONTROL: rate control was initialized for this station.
67 * @WLAN_STA_TOFFSET_KNOWN: toffset calculated for this station is valid.
68 * @WLAN_STA_MPSP_OWNER: local STA is owner of a mesh Peer Service Period.
69 * @WLAN_STA_MPSP_RECIPIENT: local STA is recipient of a MPSP.
70 * @WLAN_STA_PS_DELIVER: station woke up, but we're still blocking TX
71 * until pending frames are delivered
72 * @WLAN_STA_USES_ENCRYPTION: This station was configured for encryption,
73 * so drop all packets without a key later.
74 * @WLAN_STA_DECAP_OFFLOAD: This station uses rx decap offload
75 *
76 * @NUM_WLAN_STA_FLAGS: number of defined flags
