But that's a hypervisor bug, right?  It shouldn't be sending a "connect"
event on the ethernet device if the network really isn't present.  How
about getting it fixed there, which will resolve the issues for all
guest operating systems, not just Linux.

Or, if this is something that the hyperv developers are not going to
fix, we need to document it in the code itself so that people don't try
to remove it in a few years as an "optimization".
