Subject: [ovs-discuss] NSH rules


Dear experts,
I am trying the networking-sfc with NSH support in the all-in-one Openstack 
deploying from devstack. But in my environment, the OVS always can not accept 
the NSH related flow rules from SFC driver. The following are the corresponding 
flows and the received error.

For table 5, I got:
"hard_timeout=0,idle_timeout=0,priority=0,cookie=18389747003163845,table=5,dl_dst=fa:16:3e:d3:ad:66,eth_type=2048,actions=encap(hdr=nsh,prop(class=nsh,type=md_type,val=1)),set_field:0x1->nsh_spi,set_field:0xff->nsh_si,encap(hdr=ethernet),mod_vlan_vid:16,,resubmit(,10)"
  -O openflow13
We got Encap header nsh not support

For table 10, I got:
 
hard_timeout=0,idle_timeout=0,priority=1,cookie=1291058868797254279,nsh_spi=1,nsh_mdtype=1,eth_type=35151,table=10,dl_dst=fa:16:3e:c8:ed:35,dl_vlan=17,nsh_si=255,actions=strip_vlan,move:NXM_OF_ETH_DST->OXM_OF_PKT_REG[0..47],decap(),decap(),move:OXM_OF_PKT_REG[0..47]->NXM_OF_ETH_DST,output:40;
 Stdout: ; Stderr: ovs-ofctl: -:1: OXM_OF_PKT_REG[0..47]: unknown field 
`OXM_OF_PKT_REG'

I saw the bug log of https://bugs.launchpad.net/networking-sfc/+bug/1753349. 
All of the corresponding rules can be well inserted. I have tried the OVS from 
2.8.1 to 2.9.0 by installing via apt-get or building from source. The result is 
the same. I would lie to ask if any further configuration need to set on my 
OVS? Thanks in advance.

Blessings
