Personally I'm less fussed about WAN / LE support. Anyone with any
sense will run ixp4xx boards doing such a specialised network
operation as BE. Also, NSLU2-Linux can't test this functionality with
our LE setup as we don't have this hardware on-board. You may just
want to declare a depends on ARMEB in Kconfig (with or without OR
(ARM || BROKEN) ) and have done with it - it's up to you.

Christian Hohnstaedt's work did support LE though.

Not all ixp4xx boards are by definition "doing such a specialised
network operation".

I was always curious, why do people want to run ixp4xx in LE mode? What
are the benefits that overweight the obvious performance degradation?

I guess the main reason, at least for me, is that there is only one 
distro that properly supports LE ARM: Debian.

It greatly simplifies management/administration of a higher number of 
devices, given the fact that Debian also supports other architectures 
(not just x86/64, sometimes PPC, like most distros do).


Not always network performance is to most important factor.
