I had an fxp0 that the mounting bracket was a little long and the
pressure of screwing it down messed things up. I would get 10MB/s out
but only 10KB/s into that system. It was dropping 300-700 bytes in
some packets. I found out last night that I could remove the screw and
it worked just fine. An old 3C905-TX didn't have the problem either
but I only got 8-9MB/s. A spare fxp0 also didn't have the problem and
it was 11MB/s both directions.
