Add mac-telnet - a layer 2 Telnet/SSH server useful to access bricked devices
This package adds the mac-telnet server, client, ping and discovery utilities. See https://github.com/aouyar/MAC-Telnet for details. This package uses the fork from https://github.com/jow-/MAC-Telnet as source, the code there has a number of bugfixes and results in smaller binaries since most core functionality has been ported to libubox facilities provided by OpenWrt.
