The Ethernet MACs found on SpacemiT K1 appears to be a custom design that only superficially resembles some other embedded MACs. SpacemiT refers to them as "EMAC", so let's just call the driver "k1_emac". Supports RGMII and RMII interfaces. Includes support for MAC hardware statistics counters. PTP support is not implemented.

If you have a network (Ethernet) device belonging to this class,

say Y.

Note that the answer to this question does not directly affect

the kernel: saying N will just cause the configurator to skip all

the questions regarding SpacemiT devices. If you say Y, you will

This driver supports the Ethernet MAC in the SpacemiT K1 SoC.
|
|
|
|
To compile this driver as a module, choose M here: the module
|

will be called k1_emac.
