Clone of http://git.osmocom.org/osmocom-bb, extended by a virtual-layer-1.
The virtual layer was used in combination with osmo-mitm for the validation of the Man-in-the-Middle attack developed in my master thesis.
The code from the virtual layer in this repository is no longer maintained her, as it has been adopted in http://git.osmocom.org/osmocom-bb by Harald Welte. Thanks.
