[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.
