MEMBERS¶
typetype 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. Internally it
is write-protected by sdata_lock and local->mtx so holding either is fine
for read access.
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.AUTHOR¶
