# This is a util function to translate debian based distro interface blobs as
# given in /etc/network/interfaces to an *somewhat* agnostic format for
# distributions that use other formats.
#
# TODO(harlowja) remove when we have python-netcf active...
#
# The format is the following:
# {
#    <device-name>: {
#        # All optional (if not existent in original format)
#        "netmask": <ip>,
#        "broadcast": <ip>,
#        "gateway": <ip>,
#        "address": <ip>,
#        "bootproto": "static"|"dhcp",
#        "dns-search": <hostname>,
#        "hwaddress": <mac-address>,
#        "auto": True (or non-existent),
#        "dns-nameservers": [<ip/hostname>, ...],
#    }
# }
#
# Things to note, comments are removed, if a ubuntu/debian interface is
# marked as auto then only then first segment (?) is retained, ie
# 'auto eth0 eth0:1' just marks eth0 as auto (not eth0:1).
#
# Example input:
#
# auto lo
# iface lo inet loopback
#
# auto eth0
# iface eth0 inet static
#         address 10.0.0.1
#         netmask 255.255.252.0
#         broadcast 10.0.0.255
#         gateway 10.0.0.2
#         dns-nameservers 98.0.0.1 98.0.0.2
#
# Example output:
# {
#     "lo": {
#         "auto": true
#     },
#     "eth0": {
#         "auto": true,
#         "dns-nameservers": [
#             "98.0.0.1",
#             "98.0.0.2"
#         ],
#         "broadcast": "10.0.0.255",
#         "netmask": "255.255.252.0",
#         "bootproto": "static",
#         "address": "10.0.0.1",
#         "gateway": "10.0.0.2"
