* upgrade ixp4xx to 2.6.23.12
* upgrade to the new ethernet driver (temporary breaks Marvell switch support on Compex units) * handle NPE microcodes in a user friendly way - YAY for Intel for changing the license * add support for the Lanready AP1000 (used in for example the Ligowave LGO2AGN) git-svn-id: svn://svn.openwrt.org/openwrt/trunk@10016 3c298f89-4303-0410-b956-a3cf2f4a3e73
