Subject: [PATCH] base-files: introduce /lib/functions/network.sh This file
will contain common procedures to deal with network interfaces. Initially
provides network_get_ipaddr(), network_get_ipaddr6(), network_get_subnet()
and network_get_subnet6() to determine the primary IP addresses or subnets of
a given logical interface.
