File kdump-net-0013-bond-from-wicked.patch of Package kdump

From: Petr Tesarik <ptesarik@suse.com>
Date: Fri, 2 Sep 2016 16:52:11 +0200
Subject: Prefer wicked configuration for bonding interfaces
References: bsc#980328
Patch-mainline: v0.8.16
Git-commit: 9d6665fbb45395ee78659603bb3ddfc44d1790b7

This is ugly, because wicked parses the bonding options in its own
way, so it is necessary to translate them back to the option names
understood by the kernel.
