userspace: Enable TSO support for non-DPDK.
This patch enables TSO support for non-DPDK use cases, and
also add check-system-tso testsuite. Before TSO, we have to
disable checksum offload, allowing the kernel to calculate the
TCP/UDP packet checsum. With TSO, we can skip the checksum
validation by enabling checksum offload, and with large packet
size, we see better performance.
Consider container to container use cases:
iperf3 -c (ns0) -> veth peer -> OVS -> veth peer -> iperf3 -s (ns1)
And I got around 6Gbps, similar to TSO with DPDK-enabled.
