From 4fea49a79ece30f27ce3bb8fa9dd2a19e354e750 Mon Sep 17 00:00:00 2001 From: Alexandra Winter Date: Thu, 10 Sep 2020 19:23:44 +0200 Subject: s390/cio: Add new Operation Code OC3 to PNSO Add support for operation code 3 (OC3) of the Perform-Network-Subchannel-Operations (PNSO) function of the Channel-Subsystem-Call (CHSC) instruction. PNSO provides 2 operation codes: OC0 - BRIDGE_INFO OC3 - ADDR_INFO (new) Extend the function calls to *pnso* to pass the OC and add new response code 0108. Support for OC3 is indicated by a flag in the css_general_characteristics.
