: I have a problem with a D-Link DFE-670TXD which is handled by if_ed :
: the link state is constantly going down and up :
: Apr 28 14:21:33 iut-mir-o kernel: ed0: link state changed to DOWN
: Apr 28 14:21:35 iut-mir-o kernel: ed0: link state changed to UP
...
: the problem appear with the following commit :
: SVN rev 190643 on 2009-04-02 16:58:45Z by imp (CVS rev 1.126)
: I do not see any link state change if I revert the commit.

Doh!

I needed to force auto negotiation for other cards to work.  Let me
see if I can dig up the DFE-670TXD and go from there...  Are you also
seeing really horrible network performance as well?  Do you see this
only under load, or just at idle?
