help
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).

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.

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.
