From: Erez Shitrit <ere...@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.
Fixes: 405242c52dd5 ("net/mlx5/hws: add rule object")
