|  | If you have a network (Ethernet) card belonging to this class, say Y. | 
|  | Make sure you know the name of your card. Read the Ethernet-HOWTO, | 
|  | available from <http://www.tldp.org/docs.html#howto>. | 
|  |  | 
|  | 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. |
