[dpdk-dev] [PATCH v6 2/2] app/test_pmd: fix DCB configuration

Data Centre Bridge (DCB) configuration fails when SRIOV is
enabled if nb_rxq and nb_txq are not set to 1.

When dcb_mode is DCB_VT_ENABLED set nb_rxq and nb_txq to 1.

The failure occurs during configuration of the ixgbe PMD when
it is started, in the ixgbe_check_mq_mode function, if nb_rxq
and nb_txq are not set to 1.
