[ovs-dev] [PATCH] netdev-dpdk: Provide explicit flag to rte_vhost_driver_register

[Ciara Loftus]

rte_vhost_driver_register accepts a 'mode' flag which sets server(0) or
client(1) mode. vHost devices are registered in 'server' mode (0) when
initially created. Before this patch the flags provided to this
function were the device's 'vhost_driver_flags' which hadn't been set
yet when the register function is called but happen to be zero. Provide
an explicit flag instead for better practice.

Fixes: ("c1ff66ac80b5: netdev-dpdk: vHost client mode and reconnect")
