On some environments, such as certain SR-IOV VF configurations, RoCE
isn't supported for mlx4 Ethernet ports. Currently the driver will
not open IB device on that port.
This is problematic since we do want user-space RAW Ethernet QPs functionality
to remain in place. For that end, enhance the relevant driver flows such that we
do create a device instance in that case.
