From efaa5b05dfb3578999c31a1bbbc053706ec89ddb Mon Sep 17 00:00:00 2001

Subject: [PATCH] ifcfg/write-ifcfg.sh: bind bond and bridge interfaces to HW
either by s390 SUBCHANNELS or HWADDR, if the interface name is not
persistent.
Previously, this was bound unconditionally with HWADDR.
(cherry picked from commit 80043e21c16db168ad087a162f1fa97cae866c8d)
