Comment 2 for bug 1771296

Charm should add the parameters and set them as follows:

/etc/contrail/supervisord_vrouter_files/contrail-vrouter-dpdk.ini

command=taskset <coremask> /usr/bin/contrail-vrouter-dpdk --vr_mempool_sz <vr_mempool_size> --dpdk_txd_sz <dpdk_txd_sz> --dpdk_rxd_sz <dpdk_rxd_sz>

and MTU for vhost0 in the respective /etc/network(.d) interfaces file.

Default should not define those parameters (in which case vrouter DPDK uses defaults).
