[U-Boot-Users] Linux commit a6c05c3d changes IP autoconfig behaviour

[Wolfgang Denk]

Dear Ben,

git commit a6c05c3d in the Linux kernel tree changes behaviour of the
IP autoconfiguration in Linux:

commit a6c05c3d064dbb83be88cba3189beb5db9d2dfc3
Author: Simon Horman <horms at verge.net.au>

    [IPV4]: Fix ip command line processing.
    
    Recently the documentation in Documentation/nfsroot.txt was
    update to note that in fact ip=off and ip=::::::off as the
    latter is ignored and the default (on) is used.
    
    This was certainly a step in the direction of reducing confusion.
    But it seems to me that the code ought to be fixed up so that
    ip=::::::off actually turns off ip autoconfiguration.
    
    This patch also notes more specifically that ip=on (aka ip=::::::on)
    is the default.

It seems we have to change all "ip=...off" strings in U-Boot to
"ip=...on", as it was attempted in this patch (sorry, it's *big*):

ftp://ftp.denx.de/pub/tmp/Adapt_to_new_IP_autoconfig_policy_in_Linux.patch

However, I'm not sure if this is the right approach (and what it
actually means in terms of backward compatibility).

What do you think?

Best regards,

Wolfgang Denk
