Thank you very much. I found If I enable it, the flows with flow-mask will be installed in kernel. Otherwise, the flow with no flow-mask wil be installed. But I could not understand how to calculate the mask should be used. If only one NORMAL rule exists, and I enabled megaflow, when one virtual machine ping another one, the flows bellow are installed.
root@comm:~# ovs-dpctl dump-flows skb_priority(0),in_port(9),eth(src=fa:16:3e:49:a8:9b,dst=fa:16:3e:99:79:7f),eth_type(0x0800),ipv4(src=192.168.10.2/0.0.0.0,dst=192.168.10.4/0.0.0.0,proto=1/0,tos=0/0,ttl=64/0,frag=no/0xff), packets:426, bytes:41748, used:0.692s, actions:11 skb_priority(0),in_port(11),eth(src=fa:16:3e:99:79:7f,dst=fa:16:3e:49:a8:9b),eth_type(0x0800),ipv4(src=192.168.10.4/0.0.0.0,dst=192.168.10.2/0.0.0.0,proto=1/0,tos=0/0,ttl=64/0,frag=no/0xff), packets:426, bytes:41748, used:0.692s, actions:9 So why the frag flag and the in_port/src mac/dst mac are not masked?
