Subject: net-next-2.6 [Patch 0/2] dccp: Fix issues in setting the MPS

Hi Dave,

can you please consider this update, changes are summarized below and
patches have been in the test tree for a long while - it builds upon the
feature-negotiation infrastructure.

Gerrit


Patch summary:
--------------
The set fixes issues in setting the Maximum Packet Size (aka MSS/MTU).

Making efficient use of available packet space is even more important in
DCCP than in UDP, since fragmentation is discouraged as per RFC 4340, 14.


Patch #1: Computes MPS for common data-packet options and dynamically 
	  adapts this value depending on negotiated features.
Patch #2: Fixes a problem that arises for the MPS due to the overlap of
	  half-established and established connection phases in DCCP.
