   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.

  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.

  33           module ( = code which can be inserted in and removed from the running
  34           kernel whenever you want). The module will be called bfin_mac.
