Subject: net-next-2.6 [PATCH 0/5] dccp: Feature negotiation - continuation of Part II (core)

Hi Dave,

please find in this set the continuation. The patches have been tested to
compile standalone, with sparse checking enabled.

Gerrit


Commit summary:
---------------
This is a continuation of an ongoing submission to provide feature/capability
negotiation for DCCP endpoints (RFC 4340).

The whole set is structured into 3 main blocks - (1) basis, (2) core,
(3) integration and cleanup.

This set continues within the second part (core implementation). I have split
it in such a way that up until here the old code and the new API can co-exist.

In the next (and last) patch set within this block, the old code is step-by-step
superseded by the new API.

The full integration of the new API and clean-up of the old code then happens
in the concluding part (3).


List of patches in this set:
----------------------------
Patch #1: Set/getsockopt support to negotiate CCIDs with the peer.
Patch #2: Socket API to query the current CCID from userspace.
Patch #3: Prepares the variable-length htonl/ntohl functions for 48 bits.
          Such a length is needed by e.g. the Sequence Window feature.
Patch #4: Support for DCCP `Mandatory' type options (RFC 4340, 5.8.2).
Patch #5: Routine to insert feature-negotiation header options.
