Re: Fixes for kern/40018 -- any chance of getting these pulled into the -current and 5.x trees?

        Hello.  Is this something you can reproduce easily?  I wonder if the
ethernet chip is just hanging, and the rest of the machine is fine?
Which bits are you turning on?  just:
ip4csum, tcp4csum and udp4csum?
        If the two machines have different revisions of the chip, that
could explain why one works and the other doesn't.  I suspect that you
might be tripping over a chip bug, rather than a driver bug.
