Hi All, We've been running a number of FreeBSD boxes with high packet throughputs using polling mode. This seems to work great (gets rid of 90k odd interrupts a second). Is there any easy way of finding out how many packets are being 'dropped' in this system? (We use em Intel Pro 1000TX cards) - as obviously, there is a finite limit to the number of packets the system can push - is there any mechanism, or flag, or anything that will warn you if by the time the drivers get to poll the card, it's overflowed/lost packets? Thanks, -Karl
