That's true. But if we bring this one in prefix then while parsing the 
command and checking if a command already exist or not might need some 
additional changes. Like user can give or might not give link_id. So 
conditionally we have to check and parse. Then get to that actual 
command and see if command exist or not.

Yeah but since now we have MLD level socket, user would want to get info 
from any one of underlying link from the MLD level socket itself right?
For example assume MLD level socket is opened in an interactive way.
Now first user might wanna check how many STAs on link 0. Next want to 
check status of link 1 but without disconnecting from the interactive shell.
