From 727ecc5faaf6e976fc841649821c865ebd1e822d Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Wed, 26 Sep 2007 11:26:04 -0300 Subject: [PATCH] [DCCP]: Add FIXME for send_delayed_ack This adds a FIXME to signal that the function dccp_send_delayed_ack is nowhere used in the entire DCCP/CCID code. Using a delayed Ack timer is suggested in 11.3 of RFC 4340, but it has also rather subtle implications for the Ack-Ratio-accounting. CCID2 does not use this (maybe it should). I think leaving the function in is good, in case someone wants to implement this.
