waleed mousa 12089a526e Add support for direct ports with QoS in OVS

Today OVS mechanism driver can bind Direct port see [1] for OVS hardware
offloads.
OVS was extended with tc-offload to support rate limit see [2].
The OVS QoS driver [3] is limited to work only with Normal Ports, so we
can't put QoS rules on direct port.
This patch proposes to add support in OVS QoS driver for direct ports.
The mechanism to enforce such policies is the same with normal and
hardware offloaded direct ports.
