FYI, in case you, or anyone you know, are using a 3Com NIC in their Linux box and are seeing lots of dropped packets. If your driver is compiled static, the option has to be added to the boot args.

I had the same problem with 3Com cards at a previous job. Add this line to your /etc/conf.modules file, to add these options to the kernel driver: options 3c59x max_interrupt_work=10000 It strangely defaults to 20, which is much too small. The driver fails if more than this number of packets arrive per interrupt. Increase this number to a huge value that will never be reached. Some say there might be a drawback to using such a large value, but I have never had problems with it in my experience. Josh -- Douglas J.
