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 four bits are variable then set it to 00-00-00-00-00-0f. The actual variable bits shall be determined by the interfaces added, with interfaces not matching the mask being rejected to be brought up.
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
Maximum number of MAC addresses that the device supports for ACL.
wiphy flags, see enum wiphy_flags
wiphy regulatory flags, see enum ieee80211_regulatory_flags
features advertised to nl80211, see enum nl80211_feature_flags.
extended features advertised to nl80211, see enum nl80211_ext_feature_index.
AP SME capabilities, flags from enum nl80211_ap_sme_features.
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
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.
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.
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 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.
mask of the valid values
length of the extended capabilities
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.
(virtual) struct device for this wiphy
helps synchronize suspend/resume with wiphy unregister
debugfs directory used for this wiphy, will be renamed automatically on wiphy renames
Specify what ht_cap values can be over-ridden. If null, then none can be over-ridden.
Specify what VHT capabilities can be over-ridden. If null, then none can be over-ridden.
the network namespace this wiphy currently lives in
wireless extension handlers
packet coalescing support information
array of vendor commands supported by the hardware
array of vendor events supported by the hardware
number of vendor commands
number of vendor events
maximum number of associated stations supported in AP mode (including P2P GO) or 0 to indicate no such limit is advertised. The driver is allowed to advertise a theoretical limit that it can reach in some cases, but may not always reach.
Number of supported csa_counters in beacons and probe responses. This value should be set if the driver wishes to limit the number of csa counters. Default (0) means infinite.
max offset of between the channel on which the frame was sent and the channel on which the frame was heard for which the reported rssi is still valid. If a driver is able to compensate the low rssi when a frame is heard on different channel, then it should set this variable to the maximal offset for which it can compensate. This value should be set in MHz.
driver private data (sized according to wiphy_new
parameter)
