Build Update for williamtu/ovs-travis
-------------------------------------

Build: #415
Status: Passed

Duration: 41 mins and 14 secs
Commit: 70429d5 (tso-v9)
Author: William Tu
Message: 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.

---
v9:
  - make naming of flags more clear
v8:
  - make some namings more clear

v7: more refactoring on functions
  - rss and flow mark related functions.
  - dp_packet_clone_with_headroom
  - fix definitions of DP_PACKET_OL_FLOW_MARK_MASK
  - travis: https://travis-ci.org/github/williamtu/ovs-travis/builds/663658338

v6: fix indentation

v5: feedback from Flavio
  - move some code around, break the long line
  - travis is now working
    https://travis-ci.org/github/williamtu/ovs-travis/builds/661607017

v4:
  - Avoid duplications of DPDK and non-DPDK code by
    refactoring the definition of DP_PACKET_OL flags
    and relevant functions
  - I got weird error in travis (I think this is unrelated)
    https://travis-ci.org/github/williamtu/ovs-travis/builds/661313463
    sindex.c:378:26: error: unknown type name ‘sqlite3_str’
    static int query_appendf(sqlite3_str *query, const char *fmt, ...)
  - test compile ok on dpdk and non-dpdk, make check-system-tso still
    has a couple fails

v3:
  - fix comments and some coding style
  - add valgrind check
  - travis: https://travis-ci.org/williamtu/ovs-travis/builds/660394007
v2:
  - add make check-system-tso test
  - combine logging for dpdk and non-dpdk
  - I'm surprised that most of the test cases passed.
    This is due to few tests using tcp/udp, so it does not trigger
    TSO.  I saw only geneve/vxlan fails randomly, maybe we can
    check it later.
