The mlx4 device requires adding IB flow spec to rules that apply over infiniband link layer. This patch adds a mechanism to add such a rule. If higher levels e.g. IP/UDP/TCP flow specs are provided, the device requires us to add an empty wild-carded IB rule. Furthermore, the device requires the QPN to be put in the rule. Add here specific parsing support for IB empty rules and the ability to self-generate missing specs based on existing ones.
