}; permanent MAC address of this device
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
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.
bitmasks of frame subtypes that can be subscribed to or transmitted through nl80211, points to an array indexed by interface type
Valid interface combinations array, should not list single interface types.
number of entries in iface_combinations array.
bitmask of software interface types, these are not subject to any restrictions since they are purely managed in SW.
number of addresses in addresses.
bitmask of interfaces types valid for this wiphy, must be set by driver
wiphy flags, see enum wiphy_flags
signal type reported in struct cfg80211_bss.
each BSS struct has private data allocated with it, this variable determines its size
maximum number of SSIDs the device can scan for in any given scan
maximum number of SSIDs the device can scan for in any given scheduled scan
maximum number of match sets the device can handle when performing a scheduled scan, 0 if filtering is not supported.
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
same as max_scan_ie_len, but for scheduled scans
number of supported cipher suites
supported cipher suites
Retry limit for short frames (dot11ShortRetryLimit)
Retry limit for long frames (dot11LongRetryLimit)
Fragmentation threshold (dot11FragmentationThreshold); -1 = fragmentation disabled, only odd values >= 256 used
RTS threshold (dot11RTSThreshold); -1 = RTS/CTS disabled
current coverage class
firmware version for ethtool reporting
hardware version for ethtool reporting
WoWLAN support information
Maximum time a remain-on-channel operation may request, if implemented.
maximum number of PMKIDs supported by device
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.
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.
a pointer that drivers can use to identify if an arbitrary wiphy is theirs, e.g. in global notifiers
information about bands/channels supported by this device
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
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.
