I guess we do not need to target net tree since airoha_eth driver currently supports just the LAN interface via the MT7530 DSA switch connected to GDM1 and there are no WAN interfaces officially supported (PCS/external phy is n= ot merged mainline yet, it is only available in OpenWrt). >=20 > And at any rate, could you add some description of the before and after > behaviour? Theoretically, before this patch, GDM ports were equally distributed between QDMA0 and QDMA1 while this patch assigns LAN interfaces to QDMA0 and WAN interface to QDMA1. However, for the reason explained above, this change is not currently visible to the user.
