Return whether this system has klibc initramfs network config or not
Will return True if:
(a) klibc files exist in /run, AND
(b) either:
(i) ip= or ip6= are on the kernel cmdline, OR
(ii) an open-iscsi interface file is present in the system

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:

Return v1 network config for initramfs-configured networking (or None)
This will consider each _INITRAMFS_CONFIG_SOURCES entry in turn, and return
v1 network configuration for the first one that is applicable. If none are
applicable, return None.
