Message-Id: <11971083881748-git-send-email-gerrit@erg.abdn.ac.uk>
Date: Sat, 8 Dec 2007 10:06:27 +0000
From: Gerrit Renker <gerrit@....abdn.ac.uk>

Subject: [PATCH 7/8] [TFRC]: CCID3 (and CCID4) needs to access these inlines
This moves two inlines back to packet_history.h: these are not private
to packet_history.c, but are needed by CCID3/4 to detect whether a new
loss is indicated, or whether a loss is already pending.
Signed-off-by: Gerrit Renker <gerrit@....abdn.ac.uk>
