   3 Date: Tue, 29 Jan 2008 10:03:19 +1030
   4 Subject: ixp4xx: Ethernet support for the nslu2 and nas100d boards
   5
   6 Enables the new ixp4xx qmgr and npe drivers in ixp4xx_defconfig.
   7
   8 Sets up the corresponding platform data for the nslu2 and nas100d
   9 boards, and reads the ethernet MAC address from the internal flash.
  10
  11 Tested on both little-endian and big-endian kernels.
