I don't think we're at a stage where I'm prepared to merge something--
we all agree the latest patch has serious drawbacks, and it commits us
to a suboptimal interface that is userspace-visible.
Fair enough.

Could we try to do some cleanups to the net core to make the alias
stuff less painful? eg is there any sane way to make it possible for
a device that creates 'eth0' to also create an 'iw0' alias without an
assigning an address?
Well, "alias" interfaces really don't exist. ethX:iw is really just
adding a address record (struct in_ifaddr) to ethX. So in the current
core design, adding an alias without an address is really adding the
alias with address 0.0.0.0. And I think the core net code assumes if an
in_ifaddr struct exists for a device, then its IP address is indeed valid.
So I think the changes wouldn't be small to enhance the design to add a
concept of an alias interface.
I'll look into this more though.
Steve.
