I did the following: 1) turn on tso on the server's r8169: ethtool --offload eth0 tso on 2) on the server: tcpdump -i eth0 -s 0 -w <file> 3) ftp'ed file to 100mbit client As expected the file was corrupted, and the various corrupted byte sequences also show up in the tcpdump file at the corresponding offsets. I did this with 2.6.22.14, so it does not seem to be a recent regression in .23/.24. All files can be found here: http://hoho.dyndns.org/~holger/dist/r8169-tso/ I will gladly try out any other tweaks but need some guidance as I don't know what exactly to change - maybe without NAPI for the r8169? thank you Holger -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
