21	bool "Use DTCM for hardware DMA buffers"
22	default y
23	help
24	  Place the hardware DMA buffers into DTCM for better networking
25	  performance

27config ETH_MCUX_PROMISCUOUS_MODE
28	bool "Promiscuous mode"
29	help
30	  Place the Ethernet receiver in promiscuous mode. This may be useful
31	  for debugging and not needed for normal work.

33config ETH_MCUX_RMII_EXT_CLK
34	bool "RMII clock from external sources"
35	help
36	  Setting this option will configure MCUX clock block to feed RMII
37	  reference clock from external source (ENET_1588_CLKIN)

43	  communication with MAC ENET controller. Other busses - like SPI
44	  or I2C are used instead.
