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

	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.
