I'm not entirely sure. But here is what I observed.
Bootloader sets up both the switches. And I can use all 8 ports of the
router when I boot Lede. Only the internal switch is detected and
configurable via swconfig tool
Internal switch is connected to CPU via port 5 same as Netgear R8000.
The other bit here is that I looked through the GPL source and gpio
pin 10 is labeled as EA9500_RST2LANSW_GPIO10_PIN/ResetSwitch. So when
I performed a robo reset of the pin and 5 ports (labeled 1 thru 5 on
the unit) of the 8 physical ports stopped working (no packets).

If the external switch were to be connect via dedicated ethernet
interface it should have shown up during the probe. Is in't it?
Unfortunately my understanding about network devices limits me to
investigate this further.

I'll be more than happy to perform any tests if needed.



P.S  sorry for duplicate email if you did get this first time around.
