NAME

       struct_ieee80211_hw - hardware information and state

SYNOPSIS

       struct ieee80211_hw {
	 struct ieee80211_conf conf;
	 struct wiphy * wiphy;
	 const char * rate_control_algorithm;
	 void * priv;

	 u16 queues;
	 u16 max_listen_interval;
	 s8 max_signal;
	 u8 max_rates;
	 u8 max_rate_tries;
       };

MEMBERS

       conf

	   struct ieee80211_conf, device configuration, don't 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.

       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.

       sta_data_size
	   size (in bytes) of the drv_priv data area within struct ieee80211_sta.

       queues
	   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
	   max listen interval in units of beacon interval that HW supports

       max_signal
	   Maximum value for signal (rssi) in RX information, used only when IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB

       max_rates
	   maximum number of alternate rate retry stages

       max_rate_tries
	   maximum number of tries for each stage

DESCRIPTION

       This structure contains the configuration and hardware information for an 802.11 PHY.
