MEMBERS

perm_addr[ETH_ALEN]

permanent MAC address of this device

addr_mask[ETH_ALEN]

If the device supports multiple MAC addresses by masking, set this to a mask with variable bits set to 1, e.g. if the last

addresses

If the device has more than one address, set this pointer to a list of addresses (6 bytes each). The first one will be used by default for perm_addr. In this case, the mask should be set to all-zeroes. In this case it is assumed that the device can handle the same number of arbitrary MAC addresses.

mgmt_stypes

bitmasks of frame subtypes that can be subscribed to or transmitted through nl80211, points to an array indexed by interface type

iface_combinations

Valid interface combinations array, should not list single interface types.

n_iface_combinations

number of entries in iface_combinations array.

software_iftypes

bitmask of software interface types, these are not subject to any restrictions since they are purely managed in SW.

n_addresses

number of addresses in addresses.

interface_modes

bitmask of interfaces types valid for this wiphy, must be set by driver

max_acl_mac_addrs

Maximum number of MAC addresses that the device supports for ACL.

flags

wiphy flags, see enum wiphy_flags

regulatory_flags

wiphy regulatory flags, see enum ieee80211_regulatory_flags

features

features advertised to nl80211, see enum nl80211_feature_flags.

ap_sme_capa

AP SME capabilities, flags from enum nl80211_ap_sme_features.

signal_type

signal type reported in struct cfg80211_bss.

bss_priv_size

each BSS struct has private data allocated with it, this variable determines its size

max_scan_ssids

maximum number of SSIDs the device can scan for in any given scan

max_sched_scan_ssids

maximum number of SSIDs the device can scan for in any given scheduled scan

max_match_sets

maximum number of match sets the device can handle when performing a scheduled scan, 0 if filtering is not supported.

max_scan_ie_len

maximum length of user-controlled IEs device can add to probe request frames transmitted during a scan, must not include fixed IEs like supported rates

max_sched_scan_ie_len

same as max_scan_ie_len, but for scheduled scans

n_cipher_suites

number of supported cipher suites

cipher_suites

supported cipher suites

retry_short

Retry limit for short frames (dot11ShortRetryLimit)

retry_long

Retry limit for long frames (dot11LongRetryLimit)

frag_threshold

Fragmentation threshold (dot11FragmentationThreshold); -1 = fragmentation disabled, only odd values >= 256 used

rts_threshold

RTS threshold (dot11RTSThreshold); -1 = RTS/CTS disabled

coverage_class

current coverage class

fw_version[ETHTOOL_FWVERS_LEN]

firmware version for ethtool reporting

hw_version

hardware version for ethtool reporting

wowlan

WoWLAN support information

wowlan_config

current WoWLAN configuration; this should usually not be used since access to it is necessarily racy, use the parameter passed to the suspend operation instead.

max_remain_on_channel_duration

Maximum time a remain-on-channel operation may request, if implemented.

max_num_pmkids

maximum number of PMKIDs supported by device

available_antennas_tx

bitmap of antennas which are available to be configured as TX antennas. Antenna configuration commands will be rejected unless this or available_antennas_rx is set.

available_antennas_rx

bitmap of antennas which are available to be configured as RX antennas. Antenna configuration commands will be rejected unless this or available_antennas_tx is set.

probe_resp_offload

Bitmap of supported protocols for probe response offloading. See enum nl80211_probe_resp_offload_support_attr. Only valid when the wiphy flag WIPHY_FLAG_AP_PROBE_RESP_OFFLOAD is set.

extended_capabilities

extended capabilities supported by the driver, additional capabilities might be supported by userspace; these are the 802.11 extended capabilities ("Extended Capabilities element") and are in the same format as in the information element. See 802.11-2012 8.4.2.29 for the defined fields.

extended_capabilities_mask

mask of the valid values

extended_capabilities_len

length of the extended capabilities

privid

a pointer that drivers can use to identify if an arbitrary wiphy is theirs, e.g. in global notifiers

bands[IEEE80211_NUM_BANDS]

information about bands/channels supported by this device

reg_notifier

the driver's regulatory notification callback, note that if your driver uses wiphy_apply_custom_regulatory the reg_notifier's request can be passed as NULL

regd

the driver's regulatory domain, if one was requested via the regulatory_hint API. This can be used by the driver on the reg_notifier if it chooses to ignore future regulatory domain changes caused by other drivers.

dev

(virtual) struct device for this wiphy

registered

helps synchronize suspend/resume with wiphy unregister

debugfsdir

debugfs directory used for this wiphy, will be renamed automatically on wiphy renames

ht_capa_mod_mask

Specify what ht_cap values can be over-ridden. If null, then none can be over-ridden.

vht_capa_mod_mask

Specify what VHT capabilities can be over-ridden. If null, then none can be over-ridden.

_net

the network namespace this wiphy currently lives in

wext

wireless extension handlers

coalesce

packet coalescing support information

vendor_commands

array of vendor commands supported by the hardware

vendor_events

array of vendor events supported by the hardware

n_vendor_commands

number of vendor commands

n_vendor_events

number of vendor events

priv[0]

driver private data (sized according to wiphy_new parameter)

FOUR BITS ARE VARIABLE THEN SET IT TO 00

...:00:0f. The actual variable bits shall be determined by the interfaces added, with interfaces not matching the mask being rejected to be brought up.
