	depends on HAS_MCUX_ENET
	select NOCACHE_MEMORY if HAS_MCUX_CACHE
	select ARM_MPU if CPU_CORTEX_M7
	select NET_POWER_MANAGEMENT if PM_DEVICE
	help
	  Enable MCUX Ethernet driver.  Note, this driver performs one shot PHY
	  setup.  There is no support for PHY disconnect, reconnect or
	  configuration change.

config ETH_MCUX_PROMISCUOUS_MODE
	bool "Enable 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 "Enable 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.

config ETH_MCUX_PHY_TICK_MS
	int "PHY poll period (ms)"
	default 1000
	range 100 30000
	help
	  Set the PHY status polling period.

config ETH_MCUX_PHY_EXTRA_DEBUG
	bool "Enable additional detailed PHY debug"
	help
	  Enable additional PHY related debug information related to
	  PHY status polling.

config ETH_MCUX_RX_BUFFERS
	int "Number of MCUX RX buffers"
	default 1
	range 1 16
	help
	  Set the number of RX buffers provided to the MCUX driver.

config ETH_MCUX_TX_BUFFERS
	int "Number of MCUX TX buffers"
	default 1
	range 1 1
	help
	  Set the number of TX buffers provided to the MCUX driver.

config ETH_MCUX_HW_ACCELERATION
	bool "Enable hardware acceleration"
	help
	  Enable hardware acceleration for the following:
	  - IPv4, UDP and TCP checksum (both Rx and Tx)

config PTP_CLOCK_MCUX
	bool "MCUX PTP clock driver support"
	default y
	depends on PTP_CLOCK && NET_PKT_TIMESTAMP
	help
	  Enable MCUX PTP clock support.

if PTP_CLOCK_MCUX

config ETH_MCUX_PTP_CLOCK_SRC_HZ
	int "Frequency of the clock source for the PTP timer"
	default 50000000
	help
	  Set the frequency in Hz sourced to the PTP timer.
	  If the value is set properly, the timer will be accurate.
