[ovs-dev] ovs+dpdk does not support some options of ovs-vsctl

[Na Zhu]

Hi Ben,

I reproduce this crash, there is not gdb backtrace.

After i create bridge like this:
[root at juno ~]# ovs-vsctl show
ffe31aed-853b-4a88-8036-bbda08d5303a
    Bridge br-int
        fail_mode: secure
        Port br-int
            Interface br-int
                type: internal
        Port patch-tun
            Interface patch-tun
                type: patch
                options: {peer=patch-int}
    Bridge br-tun
        fail_mode: secure
        Port "vxlan-0a3557f2"
            Interface "vxlan-0a3557f2"
                type: vxlan
                options: {df_default="true", in_key=flow,
local_ip="10.53.87.254", out_key=flow, remote_ip="10.53.87.242"}
        Port patch-int
            Interface patch-int
                type: patch
                options: {peer=patch-tun}
        Port br-tun
            Interface br-tun
                type: internal
[root at juno ~]#

I want to check the ovs route, so i issue command "ovs-appctl
ovs/route/show", the ovs-vswitchd stop running.
The log is:
[root at juno ~]# ovs-appctl ovs/route/show
