Quoting dwil...@us.ibm.com: On the patch itself, can't we just make skb_get_hash() be able to decode ARP? It seems like that is cleaner and more generic. My first thought was to make a change in skb_get_hash(). However, the comment in __skb_get_hash() state that the hash is generated fro

Hi- I have been conducting scaling tests with OVS and docker. My tests revealed that the latency of ARP packets can become very large resulting in many ARP re-transmissions and time-outs. I found the source of the poor latency to be with the handling of arp packets in ovs_vport_find_upcal
