Is this a bug fix?
If so, perhaps it is for net with a fixes tag.  
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 not
merged mainline yet, it is only available in OpenWrt).

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.
Please update the commit message. And please try harder to explain 
the patches, this happens a lot with your submissions..
