Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "Configure n_rxq DPDK port option when adding the port"
  - Configure n_rxq DPDK port option when adding the port

    On some platform, setting n_rxq option on port separately
    does not work well and causes issues like port link down,
    so changed the logic to set n_rxq DPDK port option during
    adding the port to the bridge which help to resolve
    the problem.
