[vox-tech] configure interface for tagged vlans with openvswitch

[Brian E. Lavender]

I figured it out. 

For the openvswitch I used the following configuration. The hypervisor
connects to the internal vlan. Later, you can see where I can connect
the vms to the external vlan by changing the vlan it is connected to.

```
allow-ovs br0
iface br0 inet manual 
   ovs_type  OVSBridge
   ovs_ports eth0 

allow-ovs vlan1
iface vlan1 inet dhcp
    ovs_bridge br0
    ovs_ports eth0 
    ovs_type OVSPort
    ovs_options tag=1
    ovs_extra set interface vlan1 type=internal

allow-br0 eth0
iface eth0 inet manual
   ovs_bridge br0
   ovs_type OVSPort
```

On my openwrt, I have the following. On two of the ports, it has tagged
vlans. 

```
config interface 'lan'
	option ifname 'eth0.1'
	option type 'bridge'
	option proto 'static'
	option ipaddr '192.168.1.1'
	option netmask '255.255.255.0'
	option ip6assign '60'

config interface 'wan'
	option ifname 'eth0.2'
	option type 'bridge'
	option proto 'static'
	option ipaddr '173.228.81.239'
	option netmask '255.255.255.0'
	option gateway '173.228.81.1'
	option dns '173.228.81.232 208.201.224.11'
	
config interface 'wan2' 
	option interface 'br-wan'
	option proto 'static'
	option ipaddr '192.168.2.1'
	option netmask '255.255.255.0'

config interface 'wan6'
	option ifname '@wan'
	option proto 'dhcpv6'

config switch
	option name 'switch0'
	option reset '1'
	option enable_vlan '1'

config switch_vlan
	option device 'switch0'
	option vlan '1'
	option ports '0t 2  4t 5t'

config switch_vlan
	option device 'switch0'
	option vlan '2'
	option ports '0t 1 3 4t 5t'
```

And with my xen VMs, I can connect them to the vlan of choice using the
following. 

```
#  Networking
#
dhcp        = 'dhcp'
vif         = [ 'mac=00:16:3E:D4:36:71,bridge=br0.1' ]
```

Now to get nflow data out of the switch!
