It appears that I can (almost?) completedly deadlock a TCP connection when using TSO on 2.6.13.2. My test involves trying to send 200Mbps between two interfaces. With TSO enabled (ie, the default for e1000 NICs), in less than 1 minute, there are no more packets transmitted, though it does run nice and fast untill it completely breaks :P
Only 200 Megabits per second? This is a single TCP connection?
I disabled TSO with ethtool, and now it seems to be working reliably.
Does a new TCP connection "work" or does communication remain hung? rick jones - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
