File kdump-net-0015-config-in-kdump_netif.patch of Package kdump.2364

From: Petr Tesarik <ptesarik@suse.com>
Date: Mon, 12 Sep 2016 17:25:49 +0200
Subject: Store iface configuration in global variable kdump_netif
References: bsc#980328
Patch-mainline: v0.8.16
Git-commit: 4e266df9f73481bc412c9ce3a983ea7c87b72a88

Using standard output does not allow the caller to capture both the
configuration and additional output variables, because standard
output can be saved into a variable only using a sub-shell.
