[ovs-dev] [PATCH] vswitchd: skip right number of arguments in dpdk_init()

[Ryan Wilson]

From: Daniele Di Proietto <ddiproietto at vmware.com>

rte_eal_init() returns the number of parsed dpdk arguments to skip.
dpdk_init() should add 1 to that number, because it has already skipped
the "--dpdk" argument itself.

This patch also makes sure the program name is ovs-vswitchd in
rte_eal_init() and proctitle_init().
