config STMMAC_ETH
tristate "STMicroelectronics 10/100/1000 Ethernet driver"
depends on HAS_IOMEM
select NET_CORE
select MII
select PHYLIB
select CRC32
---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 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
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).
choice
prompt "Select the DMA TX/RX descriptor operating modes"
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.
config STMMAC_RING
bool "Enable Descriptor Ring Mode"
config STMMAC_CHAINED
bool "Enable Descriptor Chained Mode"
endchoice
