Hi guys,

        I was trying to put Open vSwitch 0.90.4 in our testbed, and it
does not work because we have VLANs. On the other hand, the OpenFlow
reference implementation works properly.

        Basics :
                Open vSwitch 0.90.4 from tarball, no changes
                Debian Lenny, kernel 2.6.27.24, SMP, 64 bits

        To reproduce :
-----------------------------------------------------------
# rmmod openflow_mod
# insmod datapath/linux-2.6/openvswitch_mod.ko
insmod: error inserting 'datapath/linux-2.6/openvswitch_mod.ko': -1 Address 
already in use
# rmmod 8021q garp stp
# insmod datapath/linux-2.6/openvswitch_mod.ko
# 
-----------------------------------------------------------

        Kernel messages :
-----------------------------------------------
Open vSwitch 0.90.4, built Sep 10 2009 10:13:14
openvswitch: can't register sap for STP (probably the bridge module is loaded)
Open vSwitch 0.90.4, built Sep 10 2009 10:13:14
-----------------------------------------------

        Note that the bridge module was not loaded. Also, disabling
VLAN is not an option, as the interfaces I want to put in Open vSwitch
are VLAN endpoints.
        If you have any advice on how we can workaround that, that
would be much appreciated and I could try to hack that.

        Have fun...

        Jean
