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.

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.
