larger DHCP replies

[Ken Yap <ken@nlc.net.au>]

I think I have found the place that limits the DHCP replies to a low
576 bytes when it could be higher. Could people having problems with low
limits on the size of menus try this patch and let me know how it goes?
I have checked it into CVS so it's available from the Etherboot web
site also.
