Libiio is a library to ease the development of software interfacing
Linux Industrial I/O (IIO) devices.

http://wiki.analog.com/resources/tools-software/linux-software/libiio

v2: Simplify greatly the patch (upstream now uses CMake)
v3: Add support for IPv6 and allow installation of systemd service file
v4: Added .hash file
v5: Rework libiio.mk and init.d scripts after feedback from upstream
