Hi Dave,
please find attached a 2-part patch set to implement features required by the RFCs:
a) exchange of "non-negotiable" (NN) feature options (RFC 4340, 6.3.2), which are
used to dynamically update known parameters during an established connection;
b) use of this new API to improve the current state of the CCID-2 (RFC 4341)
implementation for updating Ack Ratio and Sequence Window features.
Both sets are thanks to the good work done by Samuel Jero.
General DCCP part:
Patch #1: introduces sender-signalling part for exchange of NN options.
Patch #2: implements the receiver-side and activation part for NN options.
Patch #3: bug-fix to send Confirm options in the RFC-specified manner.
CCID-2 part:
Patch #4: adds initial code for CCID-2 Ack Ratio exchange.
Patch #5: fixes issues with cwnd/Sequence Window relationship in CCID-2.
Patch #6: fixes a bug in incrementing the cwnd of CCID-2.
Patch #7: fixes a bug in updating Ack Ratio relative to cwnd in CCID-2.
I have also placed this in into a fresh (today's) copy of net-next-2.6, on
git://eden-feed.erg.abdn.ac.uk/net-next-2.6 [subtree 'dccp']
