The firmware can have the capability to manage the channel context
scheduling on multiple roles running on the device including Station,

to help users sharing the network with others on a single device.

The firmware is able to support the channel chanctx up to 2 interface
simultaneously running on the different channels.

Another thing to be noted is that before the driver is going sent out the
management frames, the driver has to get the privilege from the firmware
to occupy the current channel context until the frame handshake is
completed and then get the privilege back to the firmware.

wifi: mac80211: move interface config to new struct

We'll use bss_conf for per-link configuration later, so
move out all the non-link-specific data out into a new
struct ieee80211_vif_cfg used in the vif.

Some adjustments were done with the following spatch:

@@
expression sdata;
struct ieee80211_vif *vifp;
identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator };
@@
(
-sdata->vif.bss_conf.var
+sdata->vif.cfg.var
|
-vifp->bss_conf.var
+vifp->cfg.var
)

@bss_conf@
struct ieee80211_bss_conf *bss_conf;
identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator };
@@
-bss_conf->var
+vif_cfg->var

(though more manual fixups were needed, e.g. replacing
"vif_cfg->" by "vif->cfg." in many files.)

mt76: mt7921: don't enable beacon filter when IEEE80211_CONF_CHANGE_MONITOR is set

IEEE80211_CONF_CHANGE_MONITOR would be set every time even when vif runs as
sta mode.

If vif runs as sta mode, the beacon filter would be falsely enabled
earlier than the associated state.

That is not the behavior the firmware expects and also breaks the original
logic of sta mode. Thus, we only limit the operation to set the beacon
filter only for monitor mode when IEEE80211_CONF_CHANGE_MONITOR is set.
