The nslu2 needs non-free firmware for its ethernet. This is currently
distributed in the d-i installation images on slug-firmware.net.
The firmware can be downloaded from
<http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&ProductID=2100&DwnldID=1295 4&strOSs=All&OSFullName=All%20Operating%20Systems& lang=eng>
A change in the license means it's free enough for er, non-free.

The firmware is distributed by intel in the form of some C files containing a
lot of binary dataa. (Which is why the license refers to "in binary form".)
This is compiled into /lib/firmware/NPE-B using IxNpeMicrocode.h and a
Makefile, which can be downloaded from the openwrt svn repo at:
IxNpeMicrocode.h is licensed under the GPL. Which seems problimatic,
since it is #included by IxNpeMicrocode.c, which has the above license.
Is this license GPL compatible? The prohibition on reverse engineering does
not seem GPL compatible. I've mailed Christian Hohnstaedt, author of
IxNpeMicrocode.h, to see if I can get that cleared up.
