I can only speak for looking at the Intel gigabit chip datasheets and our em(4) driver somewhat, but there are registers which control the 'pass through' which IPMI uses. It could be that the bge driver is unaware of the registers Broadcom added to support IPMI. In this case we'd need to find out what they are and teach the driver not to meddle with them. Regards, BMS
