Problems with nfsroot due to ip= cmdline changes

[Ville Syrjälä]

I recently rebased my kernel tree and discovered that my nfsroot setup
no longer worked. Here's the relevat part of my cmdline:

ip=192.168.2.200:192.168.2.185:192.168.2.1:255.255.255.0::eth0:off nfsroot=192.168.2.185:/my_nfsroot,v3,tcp root=/dev/nfs

I discovered that now I had to change the autoconfiguration option to
"on" in order to make nfsroot work. I only want to specify the IP
address manually so I don't really want autoconfiguration. The current
code works since it will not try autoconfiguration when all options are
specified manually but the current behaviour does not really match the
documentation ie. now the autoconf parameter can disable the whole IP
configuration step even though the documentation says it will only
disable autoconfiguration.

Looks like these are the relevant commits:
