Thanks, I have found numerous active hobbyists using the
IXP4-based NSLU2 NAS machine for various things - mostly
non-network related as it happens, so it'll be with us for a
while I think.

IXP42x are most probably "end of life" in the commercial sense, but the
newer IXP46x/455 and even newer IXP43x are still being sold. For
example, Gateworks have a couple of IXP43x boards ("Cambria") which
I personally find interesting, for some specific applications.

There is no platform driver for Cambria in the official Linux, guess it
should be changed.
