Gerrit Renker ddebc973c5 dccp: Lockless integration of CCID congestion-control plugins
Based on Arnaldo's earlier patch, this patch integrates the standardised
CCID congestion control plugins (CCID-2 and CCID-3) of DCCP with dccp.ko:

 * enables a faster connection path by eliminating the need to always go 
   through the CCID registration lock;

 * updates the implementation to use only a single array whose size equals
   the number of configured CCIDs instead of the maximum (256);

 * since the CCIDs are now fixed array elements, synchronization is no
   longer needed, simplifying use and implementation.

CCID-2 is suggested as minimum for a basic DCCP implementation (RFC 4340, 10);
CCID-3 is a standards-track CCID supported by RFC 4342 and RFC 5348.

Datagram Congestion Control Protocol (RFC 4340)
From http://www.ietf.org/rfc/rfc4340.txt:
The Datagram Congestion Control Protocol (DCCP) is a transport
protocol that implements bidirectional, unicast connections of
congestion-controlled, unreliable datagrams. It should be suitable
for use by applications such as streaming media, Internet telephony,
and on-line games.
To compile this protocol support as a module, choose M here: the
module will be called dccp.
If in doubt, say N.

Only use this if you're hacking DCCP.
When compiling DCCP as a module, this debugging output can be toggled
by setting the parameter dccp_debug of the `dccp' module to 0 or 1.
Just say N.

tristate "DCCP connection probing"
depends on PROC_FS && KPROBES
---help---
This module allows for capturing the changes to DCCP connection
state in response to incoming packets. It is used for debugging
DCCP congestion avoidance modules. If you don't understand
what was just said, you don't need it: say N.
Documentation on how to use DCCP connection probing can be found
at http://linux-net.osdl.org/index.php/DccpProbe
To compile this code as a module, choose M here: the
module will be called dccp_probe.
