Hmmm, I'm rusty on this, its now been a year or more since I was first involved in the details, so I may need to amend this later :) But from memory, the issue is the value programmed into the MANC register by the PROM, I don't remember what bit it was, but one bit is mistakenly set, it causes the hardware to incorrectly intercept some packets. I was snowbound today, but I'll doublecheck on the detail tomorrow and amend if needed. Everyone note that this ONLY effects an 82573 NIC, so make sure of that before anything else. Cheers, Jack
