Hi,

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
Apr 28 14:21:40 iut-mir-o kernel: ed0: link state changed to DOWN
Apr 28 14:21:42 iut-mir-o kernel: ed0: link state changed to UP
Apr 28 14:22:51 iut-mir-o kernel: ed0: link state changed to DOWN
Apr 28 14:22:53 iut-mir-o kernel: ed0: link state changed to UP

I've double checked that there are no wire/switch/hub problems.

The card used to work fine with previous version of FreeBSD,
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.

Should I submit a PR ?

Thanks for your support,
