From 84a3e72c3a5c2441be46c4afba95fe5af3c370e7 Mon Sep 17 00:00:00 2001 From: Bjørn Mork Date: Tue, 25 Feb 2014 21:11:02 +0100 Subject: ipv6: log src and dst along with "udp checksum is 0" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These info messages are rather pointless without any means to identify the source of the bogus packets. Logging the src and dst addresses and ports may help a bit. Cc: Joe Perches Signed-off-by: Bjørn Mork Signed-off-by: David S.
