Update git submodules

* Update docs/submodules/samplevnf from branch 'master'
  - Support reading inline jumbo frame and dump them

    Add support for pkt_inline of jumbo frames.
    Dump the whole packet, and not a truncated packet. This might
    have a small impact on performance as the memory footprint
    is increased (by ~640K * number of tasks), resulting in potential
    higher DTLB misses.
