description: |
Maximum ethernet frame size. The current ethernet frame sizes
supported by hardware are 1518, 1536 and 10240 (jumbo frames). This
means that normally gmac will reject any frame above max-frame-size
value. The default value is 1518, which represents an usual
IEEE 802.3 ethernet frame:
Ethernet Frame [ 14 MAC HEADER | 1500 MTU | 4 FCS ] = 1518 bytes
When using value 1536 it is possible extend ethernet MAC HEADER up
to 32 bytes. The hardware have support to jumbo frames and it can be
enabled by selecting the value 10240.
max-speed:
type: int
default: 100
description: |
This specifies maximum speed in Mbit/s supported by the device. The
gmac driver supports 10Mbit/s and 100Mbit/s. Using 100, as default
value, enables driver to configure 10 and 100Mbit/s speeds.
