File kdump-net-0001-restore-bridge.patch of Package kdump.openSUSE_Leap_42.1_Update

From: Petr Tesarik <ptesarik@suse.com>

Subject: Restore bridge devices in kdump environment
References: bsc#980328
Patch-mainline: v0.8.16
Git-commit: 516128cbd0509bb96dffeaa2e483d39545085e06

While the current approach works for a typical setup, it's definitely
better to restore a bridge with all its physical devices.
