Subject: Re: need some help on a backport of r8169
Hello François,
I've been a little long, but it's done, I've tested the last patch you
sent me.
It was the patch of the 28 Feb 2007.
The result is the same as the previous. It has the time to send some
packets but quickly blocks.
Here are the ifcofnig + ethtool infos :

You asked me to remind you to check if there is a PCI-Exepress version
of the RTL8169, I do it.
And I'll soon send you the url of my patch against the r1000 driver.
One more question, does anyone know if the 2.6.21 kernel is gonna come
out soon?
