[ovs-discuss] BUG: Open vSwitch 0.90.4 can't be used with VLANs

[Jean Tourrilhes]

	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
