Fri Mar 21 05:22:42 CET 2014


This patch adds packages for luci ncm protocol support allowing setting of ncm protocol settings in luci. This package also adds a package for NCM dongle status view application.
NCM Protocol for OpenWrt can be reviewed here: https://lists.openwrt.org/pipermail/openwrt-devel/2014-March/024374.html
