Subject: ixp4xx: Ethernet support for the nslu2 and nas100d boards
Enables the new ixp4xx qmgr and npe drivers in ixp4xx_defconfig.
Sets up the corresponding platform data for the nslu2 and nas100d
boards, and reads the ethernet MAC address from the internal flash.
Tested on both little-endian and big-endian kernels.
