ip autoconfig skips ipv6 dev initialization

[Dale Farnsworth]

I've been doing some ipv6 testing here on some nfs-rooted 2.4.18 systems.
I found that ipv6 initialization isn't performed on an ipv4-autoconfigured
network device, leaving it without a link-local address.  It happens
because ip_auto_config() is executed before inet6_init() has a chance
to register to handle NETDEV_UP notifications.  This only occurs when
ipv6 support is compiled into the kernel.

A fix is to do the ipv6 initialization before ipv4 initialization.
The included patch resolved it for me.  Please apply or suggest an
alternative.

Thanks,
