Re: forcedeth as a module only?

[marvin24@gmx.de]

Hello Manfred,

I have an Asus K8N-E Deluxe (nForce3) and had problems with loosing network 
connection from time to time (every 30 minutes or so). The nic is NVENET_7 
(see lspci). Adding the DEV_NEED_LINKTIMER workaround solved the problem for 
me.
What is this workaround doing? Since I also heard of several people having 
such problems, why isn't this fix applied to all forcedeth devices?

Btw. Windows XP x86-64 has the same problem - but didn't found the source yet 
to patch ;-)

Best wishes 

Marc
