config STMMAC_ETH
tristate "STMicroelectronics 10/100/1000 Ethernet driver"
depends on HAS_IOMEM && HAS_DMA
select MII
select PHYLIB
select CRC32
select PTP_1588_CLOCK
select RESET_CONTROLLER
---help---
This is the driver for the Ethernet IPs are built around a
Synopsys IP Core and only tested on the STMicroelectronics
platforms.
if STMMAC_ETH
config STMMAC_PLATFORM
bool "STMMAC Platform bus support"
depends on STMMAC_ETH
default y
---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 DWMAC_SOCFPGA
bool "SOCFPGA dwmac support"
depends on STMMAC_PLATFORM && MFD_SYSCON && (ARCH_SOCFPGA || COMPILE_TEST)
help
Support for ethernet controller on Altera SOCFPGA
This selects the Altera SOCFPGA SoC glue layer support
for the stmmac device driver. This driver is used for
arria5 and cyclone5 FPGA SoCs.
config DWMAC_SUNXI
bool "Allwinner GMAC support"
depends on STMMAC_PLATFORM && ARCH_SUNXI
default y
---help---
Support for Allwinner A20/A31 GMAC ethernet controllers.
This selects Allwinner SoC glue layer support for the
stmmac device driver. This driver is used for A20/A31
GMAC ethernet controller.
config DWMAC_STI
bool "STi GMAC support"
depends on STMMAC_PLATFORM && ARCH_STI
default y
---help---
Support for ethernet controller on STi SOCs.
This selects STi SoC glue layer support for the stmmac
device driver. This driver is used on for the STi series
SOCs GMAC ethernet controller.
config STMMAC_PCI
bool "STMMAC PCI bus support"
depends on STMMAC_ETH && PCI
---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
bool "Enable monitoring via sysFS "
default n
depends on STMMAC_ETH && 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).
