    net: hns: add attribute port-idx-in-ae in enet node. · 406adee9
    Yisen.Zhuang\(Zhuangyuzeng\) authored
    This patch parse port-idx-in-ae in enet node. In NIC mode of DSAF, all 6
    PHYs of service DSAF are taken as ethernet ports to the CPU. The
    port-idx-in-ae can be 0 to 5. Here is the diagram:
                +-----+---------------+
                |            CPU      |
                +-+-+-+---+-+-+-+-+-+-+
                  |    |   | | | | | |
               debug debug   service
               port  port     port
               (0)   (0)     (0-5)
    
    In Switch mode of DSAF, all 6 PHYs of service DSAF are taken as physical
    ports connect to a LAN Switch while the CPU side assume itself have one
    single NIC connect to this switch. In this case, the port-idx-in-ae will
    be 0 only.
                +-----+-----+------+------+
                |                CPU      |
                +-+-+-+-+-+-+-+-+-+-+-+-+-+
                  |    |     service| port(0)
                debug debug  +------------+
                port  port   |   switch   |
                (0)   (0)    +-+-+-+-+-+-++
                              | | | | | |
                             external port
    
    when port-idx-in-ae is not exists, old attribute port-id will be used
    (only for compatible purpose, not recommended to use port-id in new code).
