3. MEMBERS ▲
struct ieee80211_conf, device configuration, donAqt use.
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.)
time (in microseconds) it takes to change channels.
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.
weight used for NAPI polling. You must specify an appropriate value here if a napi_poll operation is provided by your driver.
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 shouldnAqt 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 doesnAqt 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 Aq1Aq in specific bit means that corresponding AC is both trigger- and delivery-enabled. Aq0Aq 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.
