9	  If you have a network (Ethernet) card belonging to this class, say Y.
10	  Make sure you know the name of your card. Read the Ethernet-HOWTO,
11	  available from <http://www.tldp.org/docs.html#howto>.
12
13	  If unsure, say Y.
14
15	  Note that the answer to this question doesn't directly affect the
16	  kernel: saying N will just cause the configurator to skip all
17	  the remaining Blackfin card questions. If you say Y, you will be
18	  asked for your specific card in the following questions.
