Hello Everyone,
The performance-regression in patch 3 "net/colo-compare.c: Fix deadlock in
compare_chr_send", has been fixed in this version by putting the packets in a
queue instead of returning error. I also found and fixed some more bugs.

Benchmark results:
Client-to-server tcp:
without patch: ~63 Mbit/s
with patch: ~66 Mbit/s
Server-to-client tcp:
without patch: ~771 Kbit/s
with patch: ~702 Kbit/s

Regards,
Lukas Straub
