Subject: pretty sure that tcp-ledbat doesn't work...

I committed a patch to remove the debugging printfs from tcp-ledbat,
because, it was the only thing I could think of that could have resulted in
the behavior I saw.

This is cubic both sides:

m@cruithne:~$ netperf -l 60 -Y 90,90 -H 172.30.42.1 -t TCP_MAERTS
MIGRATED TCP MAERTS TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to
172.30.42.1 () port 0 AF_INET : demo
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec

87380  65536  65536    60.01      93.84

And this is tcp-ledbat other side, with no other traffic.

m@cruithne:~$ netperf -l 60 -Y 90,90 -H 172.30.42.1 -t TCP_MAERTS
MIGRATED TCP MAERTS TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to
172.30.42.1 () port 0 AF_INET : demo
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec

87380  65536  65536    61.01       0.29

I have 100% of cpu or so left over.

Am I inserting the module wrong or doing something else stupid?

Sorry it's taken me so long to get on this, I had sdnat enter my life...
