RDMA/mlx5: Enable decap and packet reformat on flow tables
If NIC RX flow tables support decap operation, enable it on creation, This allows to perform decapsulation of tunnelled packets by steering rules. If NIC TX flow tables support reformat operation, enable it on creation. We don't enable those capabilities on representors as the E-Switch should handle packet modification (can be configured via TC) and as current hardware can't handle both FDB and NIC flow tables with decap/packet reformat support.
