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

platforms.

|
|
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.

---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.

The stmmac entry in /sys reports DMA TX/RX rings

---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).
