NAME

struct_wireless_dev - wireless per-netdev state

SYNOPSIS

struct wireless_dev {
  struct wiphy * wiphy;
  enum nl80211_iftype iftype;
  struct list_head list;
  struct net_device * netdev;
  struct list_head mgmt_registrations;
  spinlock_t mgmt_registrations_lock;
  struct mutex mtx;
  struct work_struct cleanup_work;
  bool use_4addr;
  u8 ssid[IEEE80211_MAX_SSID_LEN];
  u8 ssid_len;
  enum wext;
#endif
};

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

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.)
