+    This hook will parse the ip= kernel command line variable and configure any
+    interfaces specified using ipconfig found in the mkinitcpio-nfs-utils package.
+    It is meant to be used alongside other hooks that need early userspace networking
+    such as, mkinitcpio-dropbear. There is also an optional netconf_timeout kernel
+    command line argument that can be used when obtaining the ip address using dhcp, so
+    that ipconfig will not hang forever waiting for an IP addres. You can nest multiple ip=
+    parameters inside a single ip= parameter, separated by : to configure multiple interfaces.
+    There is no limit on the number of interfaces configured, but the kernel cmdline size.
+    To use this hook add the netconf hook before any other hook that need networking in
+    "/etc/mkinitcpio.conf" and rebuild the initramfs.

+    There is now an optional kernel command line parameter named netconf_timeout that
+    is used to pass the timeout option to ipconfig. This is means that when using
+    ip=dhcp as a kernel command line parameter, ipconfig will not hang forever if the
+    dhcp server is unavailable.

+    You can also now nest multiple ip= parameters inside a single ip= parameter,
