| description: | |
| Number of hardware TX and RX queues. |

| max-frame-size: |
| type: int |
| default: 1518 |
| 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. |
| |
| phy-connection-type: |
| type: string |
| enum: |
| - "rmii" |
| - "mii" |
| default: "rmii" |
| description: | |
| Phy connection type define the physical interface connection between |
| PHY and MAC. The default value uses gmac register reset value, which |
| represents Reduced Media-Independent Interface (RMII) mode. |
| |
| This property must be used with pinctrl-0. |
