From: Karthikeyan Kathirvel <quic_kathirve@xxxxxxxxxxx>
Create link based control sockets to access the link based commands
through hostapd_cli. This will create the link interfaces in the name of
wlan<X>_link<X>
Example:
To fetch link 0 status from wlan0, below command can be used -
$ hostapd_cli -i wlan0 -l 0 status
On failure of link/interface selection, below error will be observed
$ hostapd_cli -i wlan0 -l 2 status
Failed to connect to hostapd - wpa_ctrl_open: No such file or directory
