	  This is the driver for the Ethernet IPs are built around a

config STMMAC_PLATFORM
	bool "STMMAC Platform bus support"
	depends on STMMAC_ETH
	---help---
	  This selects the platform specific bus support for
	  the stmmac device driver. This is the driver used
	  on many embedded STM platforms based on ARM and SuperH
	  processors.
	  If you have a controller with this interface, say Y or M here.

	  If unsure, say N.

config STMMAC_PCI
	bool "STMMAC PCI bus support (EXPERIMENTAL)"
	depends on STMMAC_ETH && PCI && EXPERIMENTAL
	---help---
	  This is to select the Synopsys DWMAC available on PCI devices,
	  if you have a controller with this interface, say Y or M here.

	  This PCI support is tested on XLINX XC2V3000 FF1152AMT0221
	  D1215994A VIRTEX FPGA board.

	  If unsure, say N.

config STMMAC_DEBUG_FS

	---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_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.

	  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.
