[ovs-dev] [PATCH 1/3] dpdk: postpone dpdk_init

[hanxueluo at 126.com]

From: Huanle Han <hanxueluo at gmail.com>

Currently, dpdk_init takes a long time and system datapath keeps
disconnecting during dpdk_init on ovs restart. Put bridge_reconfigure()
in front of dpdk_init() so that system datapath works immediately,
and dpdk datapath works on next iteration of bridge_run()
