devices interface tests: vhosst GSO support

Add gso option in create vhost interface to support gso and checksum offload. Tested with the following startup options in qemu: csum=on,gso=on,guest_csum=on,guest_tso4=on,guest_tso6=on,guest_ufo=on, host_tso4=on,host_tso6=on,host_ufo=on Type: feature Change-Id: I9ba1ee33677a694c4a0dfe66e745b098995902b8 Signed-off-by: Steven Luong <sluong@cisco.com>
