I still observe the packets not being egressed out the classifier with
Brady's patch. And in the OVS logs, I still see the Invalid argument
warning. I am using OVS 2.11.90 and Linux 4.4.0 (SFC-Demo 103). The flow
rule is shown below. Did the patch work for you? I'm not sure the out of
order actions are the problem?

cookie=0x0, duration=7464.231s, table=0, n_packets=45, n_bytes=3330,
priority=1000,tcp,in_port="veth-br",nw_src=
192.168.2.0/24,nw_dst=192.168.2.0/24,tp_dst=80
actions=encap(nsh),set_field:0x38/0xffffff->nsh_spi,set_field:255->nsh_si,set_field:0x1->nsh_c1,set_field:0x2->nsh_c2,set_field:0x3->nsh_c3,set_field:0x4->nsh_c4,encap(ethernet),load:0xc0a80114->NXM_NX_TUN_IPV4_DST[],output:"sff0-dpl"

Thanks,
JD
