Hi Jarno,
Thanks for the patch.
The problem was that after the recent changes to odp-util.c
{ovs-,ovs-appctl }dpctl do not work anymore. Here¹s a line that used to
work:
ovs-appctl dpctl/add-flow dummy@br0
"in_port(1),eth(src=00:00:00:00:00:00/00:00:00:00:00:00,dst=ff:ff:ff:ff:ff:
ff/00:00:00:00:00:00),eth_type(0x0800),ipv4(src=10.0.0.1/0.0.0.0,dst=10.1.0
.1/0.0.0.0,proto=17/0x00,tos=0x10/0,ttl=64/0,frag=no),udp(src=0/0,dst=0/0)"

After this patch (and I suppose after patch 5818 for the kernel datapath)
not only the above line works, but we¹re also able to write the flow more
concisely, like this:
ovs-appctl dpctl/add-flow dummy@br0
"in_port(1),eth_type(0x0800),ipv4(frag=no)² 2
