[PATCH]-Fixes for ipfilter.

Hi guys,

I promised some patches to get ipfilter working on sun3 arch.  
Attatched is a tarball with two minor patches and a readme.  It's only 
1K so I hope no-one screams too loud that I sent a patch to the list.

Hoping someone can incorporate this into the sun3 tree.  All that was 
needed was to make dev nodes for it and allocate a major number and put 
the hook in the arch conf.c and it seems to work ok.  I'm natting, 
routing, etc...
