Subject: [PATCH net-next] ipv6: log src and dst along with "udp checksum is 0"
Date: Tue, 25 Feb 2014 20:34:05 +0100 [thread overview]
Message-ID: <1393356845-15287-1-git-send-email-bjorn@mork.no> (raw)
These info messages are rather pointless without any means to identify
the source of the bogus packets. Logging the src and dst addresses
may help a bit.
