If you have a network (Ethernet) card belonging to this class, say Y.

If unsure, say Y.

Note that the answer to this question doesn't directly affect the

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

the remaining Blackfin card questions. If you say Y, you will be

asked for your specific card in the following questions.
