From f6282f4da5eb67e08eff94d73a1911c3a008846a Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Sun, 10 Dec 2006 00:05:12 -0200 Subject: [DCCP]: Warn when discarding packet due to internal errors This adds a (debug) warning message which is triggered whenever a packet is discarded due to send failure. It also adds a conditional, so that an interruption during dccp_wait_for_ccid is not treated as a `BUG': the rationale is that interruptions are external, whereas bug warnings are concerned with the internals.
