From 97abd83513bee191b58f095f4d683b18acce0b49 Mon Sep 17 00:00:00 2001 From: Ryan Harper Date: Fri, 9 Jun 2017 15:33:37 -0500 Subject: sysconfig: ipv6 and default gateway fixes. With this change, entries in IPV6ADDR and IPV6ADDR_SECONDARIES will now always be in format addr/prefix. When a subnet has a gateway will be written. If the gateway is ipv6, use the key IPV6_DEFAULTGW rather than GATEWAY.
