Thanks for the suggestion.  ifconfig reports the MTU as 1500 with
both kernels, so as far as I can tell from the Fedora end, that's not
the problem.  Is there somewhere else I should check it?

The filtering bridge drops ICMP (some Windows worm was creating major
ping storms a year or so ago), so running ping from here doesn't do
anything.  But I'll check with the computing facility staff tomorrow
to make sure 1500 is ok.
