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 |
