I am trying to set the CFI bit in the VLAN TCI header. The REST call
returns 200 OK, but the instruction is not sent via the OpenFlow
protocol. Only the VID and PCP are set.
Also, cfi is defined inconsistantly. In opendaylight-action-types.yang
it is defined as int32, in openflow-extensible-match.yang as boolean.
Json code, tshark packet capture, and yang parts are below:
