Actually, when GRO compares napi->dev to skb->dev?

Hmmm, I thought the code made a skb->dev comparison with the
existing SKBs in the list when checking for same-flow matches.

It doesn't, probably based upon the assumption that a NAPI
instance maps to a unique device, the very topic we're
discussing right now :-/
