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.

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

module ( = code which can be inserted in and removed from the running
