This driver CAME from a 6.X base that is thoroughly tested here at Intel, so while I appreciate your efforts, they are unnecessary. When the time comes to MFC I will handle it.

Jack, good day. I happened to make a quick and dirty patch for your latest (for the 16.05.2007) em(4) driver from 7-CURRENT. I had seen that you mentioned TSO and 6.3, so I assume that you're going to merge the driver to the RELENG_6 someday, so maybe my effort may be helpful. To my problems. I have the '82540EM Gigabit Ethernet Controller' branded card (PWLA8390MT) and I am currently expiriencing troubles with the Gigabit switch (D-Link DGS-1008, the cheap one). Plugged into that switch I have - broken packets and SSH messages 'Disconnecting: Corrupted MAC on input.' when checksumming is turned on and gigabit speed, - abyssmal rates for the HTTP downloads (about 10Mbit/sec) when checksums are turned off and the speed is gigabit again, - having switched the media on the adapter to the 100BaseTX full-duplex, but still using the same switch the speed drops to 200Kbit/sec, - using another D-Link switch (sorry, have no other brand in hand) the above situation is completely reproducible. - working in the half-duplex mode (for 10BaseT/UTP and 100BaseTX) I have no problems to reach the 90% of the theoretical bandwidth of the link via HTTP either with checksums enabled or disabled. So, the full-duplex mode is not usable to me now. If someone can help in this situation, I am all ears. I thought that new driver may introduce some fixes, but it isn't: the situation is the same. I will continue my investigations, but just in case you're interested in my port, it is available from http://codelabs.ru/patches/fbsd/em-6.5.0-initial.patch.bz2 RELENG_6 and 7-CURRENT sources were CVSupped yesterday, 16 May 2007. TSO-related stuff is completely disabled for the RELENG_6. My limited testing of the driver revealed no problems yet, but if they will arise I will report them. -- Eygene _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
