Calling netif_receive_skb() with NETIF_F_GRO bit set in netdev->features will cause confusion for user, IMHO.
As long as LRO is enabled and performed by ESXi (which it will do), I don’t think user cares for GRO. Even if we use napi_gro_receive() for such case, it degrades the performance as unnecessary cycles are spend on an already LRO'ed packet.
Can you provide some numbers to illustrate what the slow down is?
