The loopback_test utility allows various different types of bandwidth and latency tests to be performed against a greybus loopback Interface. This utility is available in the kernel tree as loopback_test, this package is called greybus_loopback_test here to fit in with the other package names in the greybus overlay.
Once built this package will build the utility in drivers/staging/greybus/tools and install it to /usr/sbin/loopback_test in the target buildroot filesystem.
