	  This is the driver for the Ethernet IPs are built around a
	  Synopsys IP Core and only tested on the STMicroelectronics
	  platforms.

	-- help
	  The stmmac entry in /sys reports DMA TX/RX rings
	  or (if supported) the HW cap register.

config STMMAC_DA
	bool "STMMAC DMA arbitration scheme"
	default n
	---help---
	  Selecting this option, rx has priority over Tx (only for Giga
	  Ethernet device).
	  By default, the DMA arbitration scheme is based on Round-robin
	  (rx:tx priority is 1:1).

config STMMAC_DUAL_MAC
	bool "STMMAC: dual mac support (EXPERIMENTAL)"
	default n
        depends on EXPERIMENTAL && STMMAC_ETH && !STMMAC_TIMER
	---help---
	  Some ST SoCs (for example the stx7141 and stx7200c2) have two
	  Ethernet Controllers. This option turns on the second Ethernet
	  device on this kind of platforms.

config STMMAC_TIMER
	bool "STMMAC Timer optimisation"
	default n
	depends on RTC_HCTOSYS_DEVICE
	---help---
	  Use an external timer for mitigating the number of network
	  interrupts. Currently, for SH architectures, it is possible
	  to use the TMU channel 2 and the SH-RTC device.

	depends on STMMAC_ETH
	---help---
	  This driver supports DMA descriptor to operate both in dual buffer
	  (RING) and linked-list(CHAINED) mode. In RING mode each descriptor
	  points to two data buffer pointers whereas in CHAINED mode they
	  points to only one data buffer pointer.
