commit 5fb3a4916c5dd8fbbc61609bfbfa1de85f6de063 Author: Sven Eckelmann sven@narfation.org Date: Wed Jul 5 17:15:10 2017 +0200

batctl: Fix error message when tcpdump packet send failed

The strerror converts the positive error code into a string. tcpdump must therefore convert the negative return code from icmp_interface_write into a positive one before using it as parameter for strerror.
