RE: linuxppc_2_4_devel on walnut

If you're trying to boot a Walnut with an NFS root, it can be done,
but things have changed a bit from earlier versions.  We have it
working on 2.4.14-pre3.

1)  You still need a command line with the nfs root directive

2)  Your .config and autoconf.h need to specify both CONFIG_ROOT_NFS
    and CONFIG_IP_PNP_BOOTP.

There may be a way to do it with command line options, but I just
said the heck with it and changed net/ipv4/ipconfig.c to set the
default value of ic_enable to 1.  It used to be default 1, but now
is default 0.

This is a litte update.

I did indeed not use the default configuration. The default
worked fine.

The problem with the network was a typo in the command line
and no problem
with the driver code but something is funny in the ip autoconf code.

So now it sets the ip and stuff over bootp but the nfsroot
fails without even
trying to go out on the wire. This was with the code from 2001-10-29.

So I updated to todays version recompiled with the default
and now I don't
get any output from the kernel even on the serial console. I
did not have
time to read thru every patch since oct 29 today so I ask is
this problem
known to exist at this point.

I tried the latest version on my walnut card and noticed two things.

1. The default configuration don't compile

2. The ethernet driver gets confused. It reports 10mb and

half duplex when it

really is 100Mb full duplex. And it reports 100Mb full

duplex when only 10Mb

half duplex exist.
