You absolutely do not get to determine this policy, none of us
do.

What matters is that by default the damn switch device being there
is %100 transparent to the user.

And the way to achieve that default is to do software routes as
a fallback.

I am not going to entertain changes of this nature which fail
route loading by default just because we've exceeded a device's
HW capacity to offload.

I thought I was _really_ clear about this at netdev 0.1
