Wow!
Unfortunalety not on my system. Even though I'm using your patched module.
Perhaps the reason is the std-lenny 2.6.26-2-686 kernel?
I think I should try to use the 2.6.32 kernel which includes the patch. What's your guess?
Is it already available as a debian-pakage? Where to download?
Sendig to atl1e is OK:
----------------------
netperf -H max -t TCP_STREAM -- -Hmax,6
TCP STREAM TEST from ::0 (::) port 0 AF_INET6 to max.horexpower.de (2001:4b88:1018:1:92e6:baff:fe48:7d3d) port 0 AF_INET6 :

bytes bytes bytes secs. 10^6bits/sec
87380 16384 16384 10.26 92.66
Receiving from atl1e with truncated IPv6 pakets:
-------------------------------------------------
netperf -H max -t TCP_MAERTS -- -Hmax,6
TCP MAERTS TEST from ::0 (::) port 0 AF_INET6 to max.horexpower.de (2001:4b88:1018:1:92e6:baff:fe48:7d3d) port 0 AF_INET6 :
