Subject: ipv6: Do not warn for informational ICMP messages, regardless of type.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ea85a0a2dc7263de733b7d1d13a433d35fcf36f7;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

There is no reason to emit a log message for these.

Based upon a suggestion from Hannes Frederic Sowa.
