Phil, why would you want Linux to have that info? You really don't want to (IMO) build operational dependencies on VSWITCH names. I have one called DEVQA that has access to a Development VLAN and a QA VLAN. If I add a management VLAN to it, I'm going to change the VSWITCH name to DEVQAMGTto reflect that, but I don't want the Linux guests to care. That's something that I manage at the z/VM level. That other stuff is architecturally part of the OSA and Linux is entitled to know it. Imagine a world where the virtual machine has only enough authority to get Linux booted up and running, and its device drivers operational. No other DIAGNOSE functions or CP commands allowed. From a security point of view, very similar to LPAR. Ah, Paradise! (Oh, waiter! The umbrella in my glass fell out. Please bring me a fresh drink.)
