  Message : accept iodevices as NACs as well Assignable PCIe devices have a root complex path and a more descriptive I/O slot path; example output from a T4-2: # ldomctl list-io | head -n2 PATH NAME /@400/@2/@0/@8 /SYS/MB/PCIE0 ldom.conf(5) `iodevice' currently accepts PATH values, which are cryptic and completely hardware specific, whereas NAME values are obvious (partially same across machines) and match physical slot labels ("0 PCIe2 x8") besides information from ILOM: /System/PCI_Devices/Add-on/Device_0 location = PCIE0 (PCIe Slot 0). Make ldom.conf `iodevice' accept either value; internally nothing changes. Rename struct iodev's path member to dev to clarify this further. OK kettenis
