Netmap/VALE: how to bridge 2 eth?

I now have 3 VMs on VMware vSphere
2 act as host
other 1 act as switch
all are ubuntu 12.04.4 x64

topo:
[host1] eth0 ----- eth0 [switch] eth1 ----- eth0 [host2]

switch eth0 & eth1: e1000 driver, iface inet "manual"
different VLAN ID, Promiscuous Mode on

I use 3.4.88 kernel and compiled kernel & netmap OK(netmap_lin.ko & patched e1000.ko)

after replace netmap's .ko(as README in netmap/LINUX)
I use
./vale-ctl -h vale0:eth0
./vale-ctl -h vale0:eth1
to bridge switch eth0 & eth1 for host1 ping to host2, but pinging get "Destination Host Unreachable"
deattached and use
./bridge -i netmap:eth0 -i netmap:eth1
is the same

please how to fix the issue act netmap as
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
ifconfig br0 up
?
(if use brctl, pinging works fine)
