Is there a link down/up event anyway?
If the interface is configured to "on hotplug" or "on cable plugged in"
or whatever the setting name is, the network scripts should do
something. Even if its not a DHCP renew.

So, what's the equivalent or similar command to "network restart" on SLES12? Could
you update the command line for the usermodehelper when porting this patch to SLES
12?

I see a /sbin/rcnetwork in SLES, which links either to
'/etc/init.d/network' or 'service'. This could be used as a quick
workaround.
