  From: Erez Shitrit <erezsh@nvidia.com>

In root tables matcher and rule need to have their port-id, otherwise
the translate function that done in dpdk layer will not get the right
attributes.
For that whenever the matcher is matching the source-port we need to get
the relevant port-id before calling the translate function.
