userspace: Enable tunnel tests with TSO.

Browse Source 
This patch enables most of the tunnel tests in the testsuite, and adds a
large TCP transfer to a vxlan and geneve test to verify TSO
functionality. Some additional changes were required to accommodate these
changes with netdev-linux interfaces. The test for vlan over vxlan is
purposely not enabled as the traffic produced by this test gives
incorrect values in the vnet header.
