[OpenWrt-Devel] [PATCH] package/config/netifd: Replace ifconfig/route with ip command

[openwrt at daniel.thecshore.com]

From: Daniel Dickinson <openwrt at daniel.thecshore.com>

ip from busybox is now standard and carrying both
sets of commands is undesirale, therefore move
the only consumer of ifconfig/route still in base
to using ip command.
