| config ETH_MCUX_USE_DTCM_FOR_DMA_BUFFER |
| bool "Use DTCM for hardware DMA buffers" |
| default y |
| help |
| Place the hardware DMA buffers into DTCM for better networking |
| performance |

| config ETH_MCUX_PROMISCUOUS_MODE |
| bool "Promiscuous mode" |
| help |
| Place the Ethernet receiver in promiscuous mode. This may be useful |
| for debugging and not needed for normal work. |

| config ETH_MCUX_RMII_EXT_CLK |
| bool "RMII clock from external sources" |
| help |
| Setting this option will configure MCUX clock block to feed RMII |
| reference clock from external source (ENET_1588_CLKIN) |
| |
| config ETH_MCUX_NO_PHY_SMI |
| bool "Do not use SMI for PHY communication" |
| help |
| Some PHY devices, with DSA capabilities do not use SMI for |
| communication with MAC ENET controller. Other busses - like SPI |
| or I2C are used instead. |

| range 6 16 |
| help |
| Set the number of RX buffers provided to the MCUX driver. |
| |
| config ETH_MCUX_PHY_RESET |
| bool "Reset the PHY at boot" |
| help |
| Reset the ethernet PHY at boot. Requires dts properties int-gpios and |
| reset-gpios to be present. |
