Hello Grischa,

I made few tests using FreeBSD HEAD(r280410) as dom0 and two domU with FreeBSD
10.1-RELEASE. The xen version is 4.6-unstable.
I successfully setup a vlan(4) interface without any problem and without the
patch you mentioned, here is the output:

Dom0:

I'm wondering, if you still have this problem, and if you can give a try with
FreeBSD HEAD.
