    net: dsa: make "label" property optional for dsa2 · 9f91484f
    Vivien Didelot authored
    In the new DTS bindings for DSA (dsa2), the "ethernet" and "link"
    phandles are respectively mandatory and exclusive to CPU port and DSA
    link device tree nodes.
    
    Simplify dsa2.c a bit by checking the presence of such phandle instead
    of checking the redundant "label" property.
    
    Then the Linux philosophy for Ethernet switch ports is to expose them to
    userspace as standard NICs by default. Thus use the standard enumerated
    "eth%d" device name if no "label" property is provided for a user port.
    This allows to save DTS files from subjective net device names.
    
    If one wants to rename an interface, udev rules can be used as usual.
    
    Of course the current behavior is unchanged, and the optional "label"
    property for user ports has precedence over the enumerated name.
