Subject: problems with e1000 and flow control

Hello,

it seems that e1000 enables flow-control (rx pause frames) even if the switch 
does not advertise flow control. This seems to get a problem as (at least 
some) switches then forward pause frames directed to the card from other 
hosts. We think there are hosts which indeed do this in the lans of our 
student halls.

I think flow control should be completely disabled by default if the switch 
does not advertise it. It still can be forced with ethtool.

Regards,
