If the switch is manageable. Force the settings to 1000baseTX fd on both
ends.

I only have a crappy non manageable 1Gbps switch, so I tested to link the
two servers with a crossed linked cable instead of through the switch. I
now seems to have no noticable problems with the cards. If I connect it to
the switch I get that link goes down and up all the time. It seems that it
cant stop negotiating for the speed and update the settings all the time.

Btw, I have the bge patch, posted earlier this month, installed. This
happens on both 5.2.1p10 and BETA6. with or without the patch.
