If I do a 'ping -s 8000' between two PC's sitting on either side of the bridge, I see a whole bunch of TX underrun errors on both NIC's of the bridge. Eventually both are put into store and forward mode. After this, I can hardly get any traffic through the bridge at all (maximum throughput I have seen is around 1kB/s). After a reboot, everything is OK again. Does anyone have any idea what is going on? (The bridge is running 4.2-RELEASE) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
