Add per-device startup config support
This change adds support for providing per-interface parameters in the startup config. Sample configuration: dpdk { dev default { num-rx-queues 3 num-tx-queues 3 } dev 0000:02:00.0 { num-rx-queues 2 num-tx-queues 2 } dev 0000:02:00.1 } Change-Id: Ia7d9ae2ac9c4fd9baaa480d061a395f8a421a722 Signed-off-by: Damjan Marion <damarion@cisco.com>
