22    description: |
23      Maximum ethernet frame size.  The current ethernet frame sizes
24      supported by hardware are 1518, 1536 and 10240 (jumbo frames).  This
25      means that normally gmac will reject any frame above max-frame-size
26      value.  The default value is 1518, which represents an usual
27      IEEE 802.3 ethernet frame:
28
29        Ethernet Frame [ 14 MAC HEADER | 1500 MTU | 4 FCS ] = 1518 bytes
30
31      When using value 1536 it is possible extend ethernet MAC HEADER up
32      to 32 bytes.  The hardware have support to jumbo frames and it can be
33      enabled by selecting the value 10240.

39      This specifies maximum speed in Mbit/s supported by the device.  The
40      gmac driver supports 10Mbit/s and 100Mbit/s.  Using 100, as default
41      value, enables driver to configure 10 and 100Mbit/s speeds.

50      Phy connection type define the physical interface connection between
