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. | |

31 | it compiled into the kernel. This driver is also available as a | |
