MEMBERS
type
- type of this virtual interface
bss_conf
- BSS configuration for this interface, either our own or the BSS we're associated to
addr[ETH_ALEN]
- address of this interface
p2p
- indicates whether this AP or STA interface is a p2p interface, i.e. a GO or p2p-sta respectively
csa_active
- marks whether a channel switch is going on
cab_queue
- content-after-beacon (DTIM beacon really) queue, AP mode only
hw_queue[IEEE80211_NUM_ACS]
- hardware queue for each AC
chanctx_conf
- The channel context this interface is assigned to, or NULL when it is not assigned. This pointer is RCU-protected due to the TX path needing to access it; even though the netdev carrier will always be off when it is NULL there can still be races and packets could be processed after it switches back to NULL.
driver_flags
- flags/capabilities the driver has for this interface, these need to be set (or cleared) when the interface is added or, if supported by the driver, the interface type is changed at runtime, mac80211 will never touch this field
debugfs_dir
- debugfs dentry, can be used by drivers to create own per interface debug files. Note that it will be NULL for the virtual monitor interface (if that is requested.)
drv_priv[0]
- data area for driver use, will always be aligned to sizeof(void *).
DESCRIPTION
Data in this structure is continually present for driver use during the life of a virtual interface.
