From 6626e3628fe42837f733d103e194c6b4473d8669 Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Tue, 20 Mar 2007 15:00:28 -0300 Subject: [PATCH] [DCCP]: More debug information for dccp_wait_for_ccid This adds more detail in the wait_for_ccid packet scheduling loop. In particular, it informs about (i) when delay is used and (ii) why a packet is discarded.
