From: Gerrit Renker <gerrit@xxxxxxxxxxxxxx> Date: Sat, 28 Feb 2009 09:38:28 +0100 > This patch resolves a long-standing FIXME to dynamically update the Maximum > Packet Size depending on actual options usage. > > It uses the flags set by the feature-negotiation infrastructure to compute > the required header option size. > > Most options are fixed-size, a notable exception are Ack Vectors (required > currently only by CCID-2). These can have any length between 3 and 1020 > bytes. As a result of testing, 16 bytes (2 bytes for type/length plus 14 Ack > Vector cells) have been found to be sufficient for loss-free situations. > > There are currently no CCID-specific header options which may appear on data > packets, thus it is not necessary to define a corresponding CCID field as > suggested in the old comment. > > Further changes: > ---------------- > Adjusted the type of 'cur_mps' to match the unsigned return type of the > function. > > Signed-off-by: Gerrit Renker <gerrit@xxxxxxxxxxxxxx> > Acked-by: Ian McDonald <ian.mcdonald@xxxxxxxxxxx> Applied. -- To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
