Aquantia AQR113C is PHY that needs loading a firmware. Some devices may
have it stored on flash and some need filesystem to provide it.
Are you aware of any MediaTek boards which do come with AQR113C but
don't bring their own dedicated firmware flash/EEPROM IC connected
directly to first PHY?
UniFi 6 LR v1/v2 (Aquantia AQR112C) and MT7988RFB (Aquantia AQR113C)
both come with a dedidated flash/EEPROM IC for the PHY firmware.
However, that firmware (esp. on the UniFi 6 LR) may of course be
outdated by now and we may want to load newer firmware from within
Linux anyway.
I'm not sure if I can verify using Linux if there is EEPROM attached to
any of two PHYs on my board. I don't believe Linux's PHY driver exposes
possibly-attached EEPROM as any Linux device.
I think however that with EEPROM present I wouldn't need Linux driver
to load PHY firmware. In my board case I need to do that which makes me
believe there is no EEPROM chip with firmware present.
