    s390/net: add pnetid support · b6ef86e9
    Ursula Braun authored
    s390 hardware supports the definition of a so-call Physical NETwork
    IDentifier (short PNETID) per network device port. These PNETIDS
    can be used to identify network devices that are attached to the same
    physical network (broadcast domain).
    
    This patch provides the interface to extract the PNETID of a port of
    a device attached to the ccw-bus or pci-bus.
    
    Parts of this patch are based on an initial implementation by
    Thomas Richter.
