However, I have been utilising LinkIT-7688 device, which has the same 1 Port Eth-LAN, and the reason I asked about configuring switch correctly is because of an error in Luci that I see when I go to Netowork -> Switch.
Hence the question on whether any other change in esw is required.
I did create another board following the same footsteps of LinkIT and Widora and the issue persists.
Regarding, Reboot am not sure whether there is any change required on DTS.. because that doesn't work. Also, this issue is only present in Master branch of OpenWRT.. and works just fine with 19.07.05.. So is this a known thing on master ?
BTW, I have another question as well.. I have not been able to figure out how mt76-phy0 comes up in /sys/class/leds .. the board I am using doesn't have LEDs in the ethernet port, if that's what It supposed to be doing.
