    net/smc: add pnetid support · 0afff91c
    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).
    
    On s390 try to use the PNETID of the ethernet device port used for
    initial connecting, and derive the IB device port used for SMC RDMA
    traffic.
    
    On platforms without PNETID support fall back to the existing
    solution of a configured pnet table.
