[issue589] VLAN issues

[Gergo Szakal]

The patch (the xl mtu and the vlan promisc) applies and compiles fine, and the warning is indeed gone. Now I found out that I should rather create separate bridge interfaces for the vlan's by ID. Let's see:

cloned_interfaces="bridge0 bridge1 vlan0 vlan1 vlan2 vlan3"
ifconfig_xl0="up"
ifconfig_xl1="up"
ifconfig_vlan2="vlan 11 vlandev xl1 up"
ifconfig_vlan3="vlan 12 vlandev xl1 up"
ifconfig_vlan0="vlan 11 vlandev xl0 up"
ifconfig_vlan1="vlan 12 vlandev xl0 up"
ifconfig_bridge0="addm vlan0 addm vlan2 up"
ifconfig_bridge1="addm vlan1 addm vlan3 up"

I get in dmesg:

bridge0: MAC address: fe:84:dc:d5:af:e8
bridge1: MAC address: 4e:26:12:cc:2c:51
vlan0: MAC address: 00:00:00:00:00:00
vlan1: MAC address: 00:00:00:00:00:00
vlan2: MAC address: 00:00:00:00:00:00
vlan3: MAC address: 00:00:00:00:00:00


ifconfig:

        options=8<VLAN_MTU>

--------------------------------------------------------------------------

When I add the physical interface on one side:

ifconfig_bridge0="addm xl0 addm vlan2 up"
ifconfig_bridge1="addm xl0 addm vlan3 up"

then it gets added to the bridge as a member, but vlan interfaces still do not get added. Let's add:

%ifconfig bridge0 addm vlan2 up
ifconfig: BRDGADD vlan2: Network is down

So vlan interfaces start as "down" and don't get added to the bridge.
