File kdump-net-0007-query-correct-iface.patch of Package kdump.openSUSE_Leap_42.1_Update

From: Petr Tesarik <ptesarik@suse.com>
Date: Thu, 1 Sep 2016 10:40:54 +0200
Subject: Query the correct interface in kdump_ip_config
References: bsc#980328
Patch-mainline: v0.8.16
Git-commit: 023b8be6d04e645ee429acb61c4312b63b2e0c50

Since the initrd interface name may differ from the running kernel's,
the latter should be passed in the ip= dracut option. However, the
current interface name is also required in kdump_ip_config and
kdump_ip6_config to query the currently assigned IP address.
