26 | * @WLAN_STA_AUTHORIZED: Station is authorized to send/receive traffic. |
27 | * This bit is always checked so needs to be enabled for all stations | |
28 | * when virtual port control is not in use. | |
29 | * @WLAN_STA_SHORT_PREAMBLE: Station is capable of receiving short-preamble | |
30 | * frames. | |
31 | * @WLAN_STA_ASSOC_AP: We're associated to that station, it is an AP. | |
32 | * @WLAN_STA_WME: Station is a QoS-STA. | |
33 | * @WLAN_STA_WDS: Station is one of our WDS peers. | |
d46e144b | 34 | * @WLAN_STA_CLEAR_PS_FILT: Clear PS filter in hardware (using the |
e039fa4a | 35 | * IEEE80211_TX_CTL_CLEAR_PS_FILT control flag) when the next |
d46e144b | 36 | * frame to this station is transmitted. |

722f069a S |

41 | * power-save mode logically to flush frames that might still | |
42 | * be in the queues | |
43 | * @WLAN_STA_PSPOLL: Station sent PS-poll while driver was keeping | |
