Update git submodules

* Update docs/submodules/vswitchperf from branch 'master'
  - ixia: Bugfixing and burst type enhancement
    
    A support for proper reporting of "Burst" traffic type was added.
    Several bugs were fixed:
    * RFC2544 Throughput - end of search condition was moved to avoid
      situation, that another iteration is executed but its results
      dropped
    * RFC2544 Throughput - pause after each iteration was added to ensure
      that all frames are cleared from buffers; It improves stability
      of results. Also "received" values are no longer higher then
      "sent" values.
    * VSPERF will report also the number of sent and received frames
    * VSPERF will correctly process send and received values - they
      were switched on several places
