I applied the patch to dpdk_merge here
https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_darball_ovs_commits_dpdk-5Fmerge&d=DwIGaQ&c=uilaK90D4TOVoH58JNXRgQ&r=BVhFA09CGX7JQ5Ih-uZnsw&m=A2_FCacqbp2moAo3HGFlTuxsjONUGhlN42OBcAuQQ6w&s=b6btPKhgvOFr2GOUYvktND6kaC6jc3fXI-mXfvNgXOU&e=
This can be backported as far back as 2.6.

After ovs-vswitchd reboots, vhost user client port status is displayed as
LINK DOWN though the traffic is OK.
The problem is that the port may be udpated while the vhost_reconfigured
is false. Then the vhost_reconfigured is updated to true. As a result,
the vhost port status is kept as LINK-DOWN.
