Hello everyone,

I am developing a new match option in the datapath. I implemented almost
everything already, but I am missing something and I don't know what nor
what is next step.

Adding the flow directly to the datapath gives the following error:
ovs-dpctl: updating flow table (Invalid argument)

The full "stack"

sudo ovs-dpctl add-flow "ovs-system"
"in_port(3),eth(src=00:00:00:00:ca:fe,dst=05:05:05:05:05:05),eth_type(0x0800),ipv4(src=
10.10.0.1/255.255.255.255,dst=10.10.0.2/255.255.255.255,proto=17/0xff,tos=0/0,ttl=64/0,frag=no/0xff),udp(src=2152/0,dst=2152/0xffff),new_match_option(11259375/0xffffffff)"
"1"

),udp(src=2152/0,dst=2152/0xffff),new_match_option(id=11259375/0xffffffff)

Any thoughts, hints or comments are appreciated.

Kind regards and keep developing!
