[PATCH] s390: introducing support in qeth for new OSA CHPID type OSN

	This patch introduces new feature in qeth:
	qeth enhancement provides the device driver support for
        the Communication Controller for Linux on System z9 and zSeries
        (CCL), which is software that enables running the Network Control
        Program (NCP) on a zSeries machine. The OSA CDLC support is based
        on a new IBM mainframe CHPID type called Open Systems Adaper for
        NCP (OSN). In case of OSN qeth communicates with the type-OSN
        OSA-card on one hand, and with the CCL-kernel-component Network
        Device Handler (NDH) on the other.
