[PATCH 1/2] Add RDMA_*_USNIC enums for the Cisco Ethernet Virtual NIC.

[Jeff Squyres]

Per off-list conversation with Roland, add some new enums for the
Cisco Ethernet Virtual NIC (it's not an RNIC/iWARP device, so it
doesn't fit in the same category as RDMA_NODE_RNIC / RDMA_TRANSPORT_IWARP).

"USNIC" = "Userspace NIC".
