Members

wiphy: pointer to hardware description
iftype: interface type
list: (private) Used to collect the interfaces
netdev: (private) Used to reference back to the netdev
mgmt_registrations: list of registrations for management frames
mgmt_registrations_lock: lock for the list
mtx: mutex used to lock data in this struct
cleanup_work: work struct used for cleanup that can't be done directly
use_4addr: indicates 4addr mode is used on this interface, must be set by driver (if supported) on add_interface BEFORE registering the netdev and may otherwise be used by driver read-only, will be update by cfg80211 on change_interface
ssid[IEEE80211_MAX_SSID_LEN]: (private) Used by the internal configuration code
ssid_len: (private) Used by the internal configuration code
mesh_id_len: (private) Used by the internal configuration code
mesh_id_up_len: (private) Used by the internal configuration code
wext: (private) Used by the internal wireless extensions compat code

Description

This structure must be allocated by the driver/stack that uses the ieee80211_ptr field in struct net_device (this is intentional so it can be allocated along with the netdev.)
