This points to the struct wiphy allocated for this
802.11 PHY. You must fill in the perm_addr and dev
members of this structure using SET_IEEE80211_DEV
and SET_IEEE80211_PERM_ADDR. Additionally, all supported
bands (with channels, bitrates) are registered here.
rate control algorithm for this hardware.
If unset (NULL), the default algorithm will be used. Must be
set before calling ieee80211_register_hw.
pointer to private area that was allocated for driver use along with this structure.
hardware flags, see enum ieee80211_hw_flags.
headroom to reserve in each transmit skb for use by the driver (e.g. for transmit headers.)
tailroom to reserve in each beacon tx skb. Can be used by drivers to add extra IEs.
size (in bytes) of the drv_priv data area within struct ieee80211_vif.
size (in bytes) of the drv_priv data area within struct ieee80211_sta.
size (in bytes) of the drv_priv data area within struct ieee80211_chanctx_conf.
size (in bytes) of the drv_priv data area
within struct ieee80211_txq.
number of available hardware transmit queues for data packets. WMM/QoS requires at least four, these queues need to have configurable access parameters.
max listen interval in units of beacon interval that HW supports
Maximum value for signal (rssi) in RX information, used
only when IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB
maximum number of alternate rate retry stages the hw can handle.
maximum number of alternate rate retry stages the hw can report back.
maximum number of tries for each stage
maximum buffer size (number of sub-frames) to be used for A-MPDU block ack receiver aggregation. This is only relevant if the device has restrictions on the number of subframes, if it relies on mac80211 to do reordering it shouldn't be set.
maximum number of subframes in an aggregate an HT driver will transmit, used by the peer as a hint to size its reorder buffer.
HW queue ID to use for offchannel TX
(if IEEE80211_HW_QUEUE_CONTROL is set)
lists which MCS information can the HW
reports, by default it is set to _MCS, _GI and _BW but doesn't
include _FMT. Use IEEE80211_RADIOTAP_MCS_HAVE_* values, only
adding _BW is supported today.
lists which VHT MCS information the HW reports,
the default is _GI | _BANDWIDTH.
Use the IEEE80211_RADIOTAP_VHT_KNOWN_* values.
netdev features to be set in each netdev created from this HW. Note only HW checksum features are currently compatible with mac80211. Other feature bits will be rejected.
This bitmap is included in (re)association frame to indicate for each access category if it is uAPSD trigger-enabled and delivery- enabled. Use IEEE80211_WMM_IE_STA_QOSINFO_AC_* to set this bitmap. Each bit corresponds to different AC. Value '1' in specific bit means that corresponding AC is both trigger- and delivery-enabled. '0' means neither enabled.
maximum number of total buffered frames the WMM AP may deliver to a WMM STA during any Service Period triggered by the WMM STA. Use IEEE80211_WMM_IE_STA_QOSINFO_SP_* for correct values.
a size of an array of cipher schemes definitions.
a pointer to an array of cipher scheme definitions supported by HW.
maximum number of frames per AC pending in all txq entries for a vif.
