struct ieee80211_hw - hardware information and state
This structure contains the configuration and hardware information for an 802.11 PHY.
: This points to the &struct wiphy allocated for this 802.11 PHY. You must fill in the and members of this structure using SET_IEEE80211_DEV() and SET_IEEE80211_PERM_ADDR(). Additionally, all supported bands (with channels, bitrates) are registered here.
: &struct ieee80211_conf, device configuration, don't use.
: 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.
: Maximum value for signal (rssi) in RX information, used only when or
: max listen interval in units of beacon interval that HW supports
: number of available hardware transmit queues for data packets. WMM/QoS requires at least four, these queues need to have configurable access parameters.
: rate control algorithm for this hardware. If unset (NULL), the default algorithm will be used. Must be set before calling ieee80211_register_hw().
: 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.
: 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
: weight used for NAPI polling. You must specify an appropriate value here if a napi_poll operation is provided by your driver.
: 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.
: 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.
