[v11,05/12] app/graph: support ethdev command line interfaces

  From: Sunil Kumar Kori <skori@marvell.com>

Adds ethdev module to configure ethernet devices.

Following commands are exposed:
 - ethdev <ethdev_name> rxq <n_queues> txq <n_queues> <mempool_name>
 - ethdev <ethdev_name> mtu <mtu_sz>
 - ethdev <ethdev_name> promiscuous <on/off>
 - ethdev <ethdev_name> show
 - ethdev <ethdev_name> stats
 - ethdev <ethdev_name> ip4 addr add <ip> netmask <mask>
 - ethdev <ethdev_name> ip6 addr add <ip> netmask <mask>
 - help ethdev
