IB/uverbs: Add support for Vxlan protocol
Add ib_uverbs_flow_spec_tunnel to define the rule to match Vxlan, the type, size, reserved fields are identical to rest of the protocols, and are used to identify the spec. The tunnel id is the vni value of the Vxlan protocol, and it is used as part of the steering rule, it is limited by the mask. The steering rule configured on the hardware does a match according to vni and other protocols. In the same way as rest of the protocols that we match, the uniq field's of each protocol are represented on the val and the mask.
