Hi Dave,

I would like to continue with the patches in the Core set, the second
out of three blocks. If the time of submission is inconvenient, please
let me know, I will then resubmit later.

Patches have been compile-tested with sparse checking enabled.

Gerrit


Commit summary:
---------------
The set begins the second set (out of three) of the feature negotiation patches,
to provide a self-contained feature negotiation API for the DCCP protocol.

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

Within these blocks, this set introduces the first parts of a new API to 
communicate feature-negotiation changes via socket options.


List of patches in this set:
----------------------------
Patch #1: Provides a mechanism to resolve CCID-dependent features. Since
          CCIDs are a server-priority feature, this is done by the server.
Patch #2: Deprecates old featneg API, as it was dangerous/clumsy.
Patch #3: Support to negotiate checksum-coverage values (as in UDP-Lite).
Patch #4: Deprecates Ack Ratio sysctl, to enable automatic updating.
Patch #5: Tidies up the setsockopt interface for new additions.

The set is also available for viewing online, beginning at
http://eden-feed.erg.abdn.ac.uk/cgi-bin/gitweb.cgi?p=dccp_exp.git;a=commitdiff;h=1a2c1...
