MLD level socket can take 'LINKID <link id>'. Add changes to pass this via
hostapd_cli. User needs to give "link_id=<link_id>" in post fix fashion in
the command in order to pass this link_id from cli.
For example -
$ hostapd_cli -i wlan0 status link_id=0 | grep freq=
freq=2437
$ hostapd_cli -i wlan0
...
Interactive mode
> ping
PONG
>
> status link_id=0
Command for 'LINKID 0'
state=ENABLED
phy=phy0
freq=2437
...
