> When creating flow rule with zero specs it will cause matching all UDP
> packets like following:
> eth / ipv4 / udp / vxlan / end
> Such rule will match all udp packets.
>
> This change the behavior to match the dv flow engine which will
> automatically set the match on relative outer UDP port if the user didn't
> specify any.
