Hello Gerrit and others,
   we compiled 2.6.27-rc4 with DCCP as module in my testbed desktop.

# modprobe -l

The module did not start in the boot (expected!). I then ran

"strace -f -e trace=network iperf -s -d -l 1424 -i 1"


# lsmod
Module                  Size  Used by
dccp_tfrc_lib          17868  0
dccp_ipv6              14916  2
dccp_ipv4              14596  3 dccp_ipv6
dccp                   58176  2 dccp_ipv6,dccp_ipv4

DCCP did not load the dccp_ccid2 module. Is this the problem?

Just to let you know:
# cat /proc/sys/net/dccp/default/rx_ccid /proc/sys/net/dccp/default/tx_ccid

I then tested tested with 2.6.27-rc8, the same as with 2.6.27-rc4.

So, what is your opinion?
