What exactly is your question/point? In the schematic you linked, P and N are swapped on the Rx pair of the Airoha PHY, hence the pnswap-rx
line in the DTS. P and N are not swapped on the GPY211.
My point is that the en8811h of openwrt one was drawn incorrectly, and then special configuration was made on dts to remedy it?
Hm, BananaPI did the same in the R3 Mini and the Arcadyan Mozart has the same property set. I supposes this was done to simplify the PCB layout?
