This probably ought to be a command line arg, my tg3 apparently
doesn't need it at all. One second is what's in the nfs-root stuff,
perhaps they need to share an arg, I changed it to two because my tlan
was dropping stuff (but not hanging - that may be a driver bug).
Ideally, I'd like to find a way to wait until the damn thing is up
before sending.

net/ipv4/ipconfig.c:
 /* Define the friendly delay before and after opening net devices */
 #define CONF_PRE_OPEN           (HZ/2)  /* Before opening: 1/2 second */
 #define CONF_POST_OPEN          (1*HZ)  /* After opening: 1 second */
 
Anyway, I'm still struggling with getting stuff working on my Opteron
box, care to take a stab at it?

I think this can probably be unconditional. Merged.
