    When ip= is seen on the kernel command line in debian initramfs
    and networking is brought up, ipconfig will populate
    /run/net-<name>.cfg.

    The files are shell style syntax, and examples are in the tests
    provided here.  There is no good documentation on this unfortunately.

    DEVICE=<name> is expected/required and PROTO should indicate if
    this is 'none' (static) or 'dhcp' or 'dhcp6' (LP: #1621507) or 'static'
    or 'off' (LP: 2065787). Note that IPV6PROTO is also written to address
    the possibility of both ipv4 and ipv6 getting addresses.

    Full syntax is documented at:
    https://git.kernel.org/pub/scm/libs/klibc/klibc.git/plain/usr/kinit/ipconfig/README.ipconfig

    This will consider each _INITRAMFS_CONFIG_SOURCES entry in turn, and return
