22  max-frame-size:
23    type: int

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

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

53      Phy connection type define the physical interface connection between
