When a former transaction was aborted by hitting Ctrl-C the old reply might
still hang in the ethernet controller making all further transactions fail.
So just skip over old replies.

An alternative would be to drain the ethernet queue before a new request is
sent. Don't know how that works and I don't see much benefit, so I didn't
try to find out :-)
