I tried a few more settings. I've reported the ones that worked for me. It
turns out that the first packet is lost if I really don't want to let my
Datapath to crash.
Cases tried with constant ping stream between two hosts attached to
different ports of the NetFPGA card:
- NOX inserts flow_mod with actions = [OFPAT_OUTPUT], bufid
- No problem
- NOX inserts flow_mod with actions = [OFPAT_SET_VLAN_VID, OFPAT_OUTPUT],
bufid
- ofpbuf assertion
- NOX inserts flow_mod with actions = [OFPAT_SET_VLAN_VID], bufid
- ofpbuf assertion
- NOX inserts flow_mod with actions = [OFPAT_SET_VLAN_VID], bufid = None
- No problem
- NOX inserts flow_mod with actions = [OFPAT_SET_VLAN_VID, OFPAT_OUTPUT],
bufid = None
- No problem
- NOX inserts flow_mod with actions = [OFPAT_SET_VLAN_VID, OFPAT_OUTPUT],
bufid = None; Follow up this FLOW_MOD with PACKET_OUT(bufid)
- ofpbuf assertion
