This failed because the guest was assigned a MAC of 5a:36:0e:fc:00:0a
and the CXFabric workaround only registers 5a:36:0e:fc:00:{01..08}. I'm
a bit confused though [0] says:

(previous 5a:36:0e:fc:00:09)
but I don't see any previous uses of select_ether in any of the other
logs for this job, certainly not 9 of them. I don't think the host can
be shared for this particular test, so I've no idea what has used all
those addresses.

This seems to be somewhat particular to the linux-linus test -- the
unstable and 4.4-testing tests seem fine.

I could just bump the number of registered MACs up, but I think it would
be better to understand what is going on. Any ideas?
