[ovs-dev] Interface reconfigure patches

[Jesse Gross]

Just in case it isn't entirely clear: "xen: Correctly write VLAN key in 
config file." is destined for master and "xen: Restore state files for 
VIF VLANs" is destined for citrix.

Both of these bugs were caused by mistakes when porting between branches 
and it makes me wonder if there is any way to simply things.  Otherwise 
I'm afraid that we are going to have subtle bugs creep in as the 
branches diverge.
