Allow the MTU of vxlan devices without an underlying device to be set to
larger values (up to a maximum based on IP packet limits and vxlan
overhead).

Previously, their MTUs could not be set to higher than the conventional
ethernet value of 1500.  This is a very arbitrary value in the context
of vxlan, and prevented such vxlan devices from being able to take
advantage of jumbo frames etc.

The default MTU remains 1500, for compatibility.

I have an internal patch which does the same thing and
was hoping to post it soon.
I am not using ovs. so, I am not closely following the thread on the other
patch in the series. But, this patch certainly stands on its own and is required.

Thanks!
