I was suggesting this since I was taking into consideration the comment 
from skbuff.c, "we can save several CPU cycles by avoiding having to 
disable and re-enable IRQs."
Is there a downside to this?

I had no idea what GRO is, so I have read about it [0] and looked at a 
couple of drivers which use it. They all seem to
replace netif_receive_skb with napi_gro_receive and when there are no 
more packets in napi_pool they call napi_gro_flush.
Is it that simple?
