The magic happens right at the end of ipconfig.c:
__setup("ip=", ip_auto_config_setup);
__setup("nfsaddrs=", nfsaddrs_config_setup);
When the kernel boots it runs init/main.c:parse_options() to parse
the kernel boot command line. The function init/main.c:checksetup()
will call ip_auto_config_setup() when it sees an argument of the
form "ip=XXXX" on the command line.
If there is no `ip=' argument then ip_auto_config_setup() will
not be called at all.
