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
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
drv_priv[0] __attribute__((__aligned__(sizeof(void *))))
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.
