[PATCH 7/9] batctl: tcpdump: don't label unknown ICMPv6 types as unreachable

[Sven Eckelmann]

The default case of the ICMPv6 type switch prints ", destination
unreachable, unknown icmp6 type (N)". Every ICMPv6 type that is not
explicitly handled is therefore mislabelled as a destination unreachable
message.

Just report "unknown icmp6 type" instead.
