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.

-- 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.

---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.
