Change colocatedAgentID mac addr to interface which needs to be treated as AL MAC

- Once AL MAC is set check the ctrl prompt whether database reset happened
Observe outputs deleting all datamodels and database insert to verify successful reset
Sample response in ctrl:
Image Removed

Response in database: Respective rows will be updated in db

Run local Agent with below cmd, (this step is not mandatory)

Prerequisites - One Time Process
Rename/delete the dnsmasq from /usr/bin
Please make sure WAN access wont be there in your Extender (for that, delete all default route entires)

Remove default onewifi db from /opt/secure/wifi
To rerun onewifi - systemctl restart onewifi
Now, check mesh backhaul connection is established or not over 5G for wifi1.1 interface .
Please use below command to check ,
- iw dev wifi1.1 info in star
- iw dev wifi1.1.sta2 info in ctrl
- iw dev wifi1.1.sta2 station dump in ctrl - this command give the Star connected client info
Once above steps are success, then run the agent at Star
systemctl start em_agent
Please wait few min, then check iw dev
All private vaps should be up and running in Ext-1 with default EasyMesh ssid's (i,e private_ssid)
Now, set brlan0 static ip addr (for ex, 10.0.0.55) in star
ping 10.0.0.1 from ext1 - should be success
Test the connected clients
