[Na Zhu]

Hi,

I am trying to use ovs dpdk, i follow the README-native-tunneling.md, it
does not work.
my setup is:

The prefix length of br-vxlan is not 24, is 25, after i create br-vxlan,
there is no route in ovs, so i add it by command ovs-appctl.
[root at juno ovs-build]# ./bin/ovs-appctl ovs/route/show
Route Table:
Cached: 10.53.87.242/32 dev br-vxlan
Cached: 127.0.0.1/32 dev lo
Cached: 158.85.164.66/32 dev bond1
Cached: 192.168.1.1/32 dev br0
Cached: 158.85.164.64/27 dev bond1
Cached: 192.168.1.0/24 dev br0
Cached: 169.254.0.0/16 dev bond1
Cached: 127.0.0.0/8 dev lo
Cached: 0.0.0.0/0 dev bond1 GW 158.85.164.65
[root at juno ovs-build]#
[root at juno ovs-build]# ./bin/ovs-appctl ovs/route/add 10.53.87.242/25
br-vxlan
OK
[root at juno ovs-build]# ./bin/ovs-appctl ovs/route/show
Route Table:
User: 10.53.87.128/25 dev br-vxlan
Cached: 10.53.87.242/32 dev br-vxlan
Cached: 127.0.0.1/32 dev lo
Cached: 158.85.164.66/32 dev bond1
Cached: 192.168.1.1/32 dev br0
Cached: 158.85.164.64/27 dev bond1
Cached: 192.168.1.0/24 dev br0
Cached: 169.254.0.0/16 dev bond1
Cached: 127.0.0.0/8 dev lo
Cached: 0.0.0.0/0 dev bond1 GW 158.85.164.65
[root at juno ovs-build]#
Then i ping 192.168.1.2, and i capture vxlan packet on eth0 by tcpdump,
there is no vxlan packet, do anyone know why?
