Enumeration members

ACCEPT_BCAST_PROBE_RESP = 18

Driver accepts broadcast probe response

ACK_SIGNAL_SUPPORT = 27

This driver/device supports (average) ACK signal strength reporting.

AIRTIME_FAIRNESS = 33

Driver supports getting airtime fairness for transmitted packets and has enabled airtime fairness scheduling.

AP_PMKSA_CACHING = 34

Driver/device supports PMKSA caching (set/del PMKSA operations) in AP mode.

BEACON_RATE_HT = 7

Driver supports beacon rate configuration (AP/mesh) with HT rates.

BEACON_RATE_LEGACY = 6

Driver supports beacon rate configuration (AP/mesh), supporting a legacy (non HT/VHT) rate.

BEACON_RATE_VHT = 8

Driver supports beacon rate configuration (AP/mesh) with VHT rates.

BSS_PARENT_TSF = 4

Per BSS, this driver reports the time the last beacon/probe was received. The time is the TSF of the BSS that the interface that requested the scan is connected to (if available).

CAN_REPLACE_PTK0 = 31

Driver/device confirm that they are able to rekey an in-use key correctly. Userspace must not rekey PTK keys if this flag is not set. Ignoring this can leak clear text packets and/or freeze the connection.

CONTROL_PORT_OVER_NL80211 = 26

Driver supports sending and receiving control port frames over nl80211 instead of the netdevice.

CQM_RSSI_LIST = 13

With this driver the %NL80211_ATTR_CQM_RSSI_THOLD attribute accepts a list of zero or more RSSI threshold values to monitor rather than exactly one threshold.

DFS_OFFLOAD = 25

HW/driver will offload DFS actions. Device or driver will do all DFS-related actions by itself, informing user-space about CAC progress, radar detection event, channel change triggered by radar detection event. No need to start CAC from user-space, no need to react to "radar detected" event.

ENABLE_FTM_RESPONDER = 32

Driver supports enabling fine timing measurement responder role.

EXT_KEY_ID = 36

Driver supports "Extended Key ID for Individually Addressed Frames" from IEEE802.11-2016.

FILS_MAX_CHANNEL_TIME = 17

Driver is capable of overriding the max channel attribute in the FILS request params IE with the actual dwell time.

FILS_SK_OFFLOAD = 14

Driver SME supports FILS shared key authentication with %NL80211_CMD_CONNECT.

FILS_STA = 9

This driver supports Fast Initial Link Setup with user space SME (NL80211_CMD_AUTHENTICATE) in station mode.

HIGH_ACCURACY_SCAN = 24

Driver supports high accuracy scan.

LOW_POWER_SCAN = 23

Driver supports low power scan.

LOW_SPAN_SCAN = 22

Driver supports low span scan.

MFP_OPTIONAL = 21

Driver supports the %NL80211_MFP_OPTIONAL value in %NL80211_ATTR_USE_MFP.

MGMT_TX_RANDOM_TA = 10

This driver supports randomized TA in @NL80211_CMD_FRAME while not associated.

MGMT_TX_RANDOM_TA_CONNECTED = 11

This driver supports randomized TA in @NL80211_CMD_FRAME while associated.

MU_MIMO_AIR_SNIFFER = 2

This device supports MU-MIMO air sniffer which means that it can be configured to hear packets from certain groups which can be configured by the %NL80211_ATTR_MU_MIMO_GROUP_DATA attribute, or can be configured to follow a station by configuring the %NL80211_ATTR_MU_MIMO_FOLLOW_MAC_ADDR attribute.

OCE_PROBE_REQ_DEFERRAL_SUPPRESSION = 20

Driver supports probe request tx deferral and suppression

OCE_PROBE_REQ_HIGH_TX_RATE = 19

Driver supports sending the first probe request in each channel at rate of at least 5.5Mbps.

RRM = 1

This driver supports RRM. When featured, user can can request to use RRM (see %NL80211_ATTR_USE_RRM) with %NL80211_CMD_ASSOCIATE and %NL80211_CMD_CONNECT requests, which will set the ASSOC_REQ_USE_RRM flag in the association request even if NL80211_FEATURE_QUIET is not advertized.

SAE_OFFLOAD = 38

Device wants to do SAE authentication in station mode (SAE password is passed as part of the connect command).

SCAN_MIN_PREQ_CONTENT = 30

Driver/device can omit all data except for supported rates from the probe request content if requested by the %NL80211_SCAN_FLAG_MIN_PREQ_CONTENT flag.

SCAN_RANDOM_SN = 29

Driver/device supports randomizing the SN in probe request frames if requested by %NL80211_SCAN_FLAG_RANDOM_SN.

SCAN_START_TIME = 3

This driver includes the actual time the scan started in scan results event. The time is the TSF of the BSS that the interface that requested the scan is connected to (if available).

SCHED_SCAN_BAND_SPECIFIC_RSSI_THOLD = 35

Driver supports filtering of sched scan results using band specific RSSI thresholds.

SCHED_SCAN_RELATIVE_RSSI = 12

The driver supports sched_scan for reporting BSSs with better RSSI than the current connected BSS (%NL80211_ATTR_SCHED_SCAN_RELATIVE_RSSI).

SET_SCAN_DWELL = 5

This driver supports configuration of channel dwell time.

STA_TX_PWR = 37

This driver supports controlling tx power to a station.

TXQS = 28

Driver supports FQ-CoDel-enabled intermediate TXQs.

VHT_IBSS = 0

This driver supports IBSS with VHT datarates.

VLAN_OFFLOAD = 39

The driver supports a single netdev with VLAN tagged frames and separate VLAN-specific netdevs added using vconfig similarly to the Ethernet case.

_4WAY_HANDSHAKE_STA_1X = 16

Device wants to do doing 4-way handshake with 802.1X in station mode (will pass EAP frames to the host and accept the set_pmk/del_pmk commands), doing it in the host might not be supported.

_4WAY_HANDSHAKE_STA_PSK = 15

Device wants to do 4-way handshake with PSK in station mode (PSK is passed as part of the connect and associate commands), doing it in the host might not be supported.
