Subject: IB/mlx5: Add match on vport when in switchdev mode
Patch-mainline: v4.17-rc1
Git-commit: 018a94eec0efc04c678f694f903e621622fd0bcf
References: bsc#1103991 FATE#326007

When we point to a representor, it means we are in switchdev mode.
The flow db is shared between PF and virtual function representors
so each rule created needs to have a match on its specific source port.
