If you have a network (Ethernet) card belonging to this class, say Y
|
|
and read the Ethernet-HOWTO, available from
|
|
<http://www.tldp.org/docs.html#howto>.
|
|
|
|
Note that the answer to this question doesn't directly affect the
|
|
kernel: saying N will just cause the configurator to skip all
|
|
the questions about ARC cards. If you say Y, you will be asked for
|
|
your specific card in the following questions.

On some legacy ARC (Synopsys) FPGA boards such as ARCAngel4/ML50x
|

non-standard on-chip ethernet device ARC EMAC 10/100 is used.

Say Y here if you have such a board. If unsure, say N.

Support for Rockchip RK3066/RK3188 EMAC ethernet controllers.
