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

  13           Note that the answer to this question doesn't directly affect the
  14           kernel: saying N will just cause the configurator to skip all
  15           the remaining Blackfin card questions. If you say Y, you will be
  16           asked for your specific card in the following questions.

  29           it compiled into the kernel. This driver is also available as a
  30           module ( = code which can be inserted in and removed from the running
