The aim of this change is to invalidate kmods which are built against a different kernel config on the opkg metadata level. Manual copying and insmod of custom *.ko files, e.g. for development purpose, is still possible. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@29686 3c298f89-4303-0410-b956-a3cf2f4a3e73
