Subject: [PATCH 22/31] [DCCP]: More debug information for dccp_wait_for_ccid
Date: Tue, 20 Mar 2007 20:16:51 -0300 [thread overview]
Message-ID: <20070320231650.GK17811@ghostprotocols.net> (raw)
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.
