MEMBERS

       mactime
	   value in microseconds of the 64-bit Time Synchronization Function (TSF) timer when the first data symbol (MPDU) arrived at the
	   hardware.

       device_timestamp
	   arbitrary timestamp for the device, mac80211 doesn't use it but can store it and pass it back to the driver for synchronisation

       ampdu_reference
	   A-MPDU reference number, must be a different value for each A-MPDU but the same for each subframe within one A-MPDU

       flag
	   RX_FLAG_*

       vendor_radiotap_bitmap
	   radiotap vendor namespace presence bitmap

       vendor_radiotap_len
	   radiotap vendor namespace length

       freq
	   frequency the radio was tuned to when receiving this frame, in MHz

       rate_idx
	   index of data rate into band's supported rates or MCS index if HT or VHT is used (RX_FLAG_HT/RX_FLAG_VHT)

       vht_nss
	   number of streams (VHT only)

       rx_flags
	   internal RX flags for mac80211

       band
	   the active band when this frame was received

       antenna
	   antenna used

       signal
	   signal strength when receiving this frame, either in dBm, in dB or unspecified depending on the hardware capabilities flags
	   IEEE80211_HW_SIGNAL_*

       ampdu_delimiter_crc
	   A-MPDU delimiter CRC

       vendor_radiotap_align
	   radiotap vendor namespace alignment. Note that the actual data must be at the start of the SKB data already.

       vendor_radiotap_oui[3]
	   radiotap vendor namespace OUI

       vendor_radiotap_subns
	   radiotap vendor sub namespace

DESCRIPTION

       The low-level driver should provide this information (the subset supported by hardware) to the 802.11 code with each received frame, in the
       skb's control buffer (cb).

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;
	 u32 flags;
	 unsigned int extra_tx_headroom;

	 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.
