File kdump-net-0017-kernel-mods-for-inactive.patch of Package kdump.openSUSE_Leap_42.1_Update

Subject: Include required kernel modules for inactive interfaces
References: bsc#980328
Patch-mainline: v0.8.16
Git-commit: 848f4d15558bb6ae82d028cc5c281e813f84889b

Dracut's network module already includes modules for bridges, bonding
and vlan, but if dracut runs with the --hostonly option, they are
included only if the corresponding module is loaded. This logic is
wrong if kdump uses a non-default interface which is not started
automatically (e.g. with STARTMODE='manual').

Make sure that all necessary kernel modules are included by calling
instmods with hostonly explicitly set to an empty string.
