With Dave's latest super-TSO patch, TCP over loopback will only be
doing order-0 allocations in the common case.  UDP and others may
still do large allocations but that logic is all localised in
ip_append_data.

So if we wanted we could easily remove most large allocations over
the loopback device.

Cheers,
