3592 tape devices are able to write data encrpyted on tape mediums. This z/Linux device driver support includes the following functions: * ioctl to switch on/off encryption * ioctl to query encryption status of drive * ioctls to set and query key encrypting keys (kekls) * long busy interrupt handling Signed-off-by: Michael Holzheu <holzheu@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
