I really doubt this adapter can process millions of packets per second ?
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 would rather enable GRO, it would be more useful.
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?
