MEMBERS
- conf
- struct ieee80211_conf, device configuration, donīt use.
- wiphy
- 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.
- workqueue
- single threaded workqueue available for driver use, allocated by
mac80211 on registration and flushed on unregistration. - rate_control_algorithm
- rate control algorithm for this hardware. If unset (NULL), the
default algorithm will be used. Must be set before calling
ieee80211_register_hw. - priv
- pointer to private area that was allocated for driver use along
with this structure. - flags
- hardware flags, see enum ieee80211_hw_flags.
- extra_tx_headroom
- headroom to reserve in each transmit skb for use by the driver
(e.g. for transmit headers.) - channel_change_time
- time (in microseconds) it takes to change channels.
- vif_data_size
- size (in bytes) of the drv_priv data area within struct
ieee80211_vif. - queues
- number of available hardware transmit queues for data packets.
WMM/QoS requires at least four. - max_rssi
- Maximum value for ssi in RX information, use negative numbers for
dBm and 0 to indicate no support. - max_signal
- like max_rssi, but for the signal value.
- max_noise
- like max_rssi, but for the noise value.
DESCRIPTION
This structure contains the configuration and hardware information for
an 802.11 PHY.
