CONFIG_ARCNET
  If you have a network card of this type, say Y and check out the
  (arguably) beautiful poetry in
  <file:Documentation/networking/arcnet.txt>.

  You need both this driver, and the driver for the particular ARCnet
  chipset of your card. If you don't know, then it's probably a
  COM90xx type card, so say Y (or M) to "ARCnet COM90xx chipset
  support" below.

  You might also want to have a look at the Ethernet-HOWTO, available
  from <http://www.linuxdoc.org/docs.html#howto>(even though ARCnet
  is not really Ethernet).

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called arcnet.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt> as well
  as <file:Documentation/networking/net-modules.txt>.

CONFIG_ARCNET_1051
  This allows you to use RFC1051 with your ARCnet card via the virtual
  arc0s device. You only need arc0s if you want to talk to ARCnet
  software complying with the "old" standard, specifically, the DOS
  arcnet.com packet driver, Amigas running AmiTCP, and some variants
  of NetBSD. You do not need to say Y here to communicate with
  industry-standard RFC1201 implementations, like the arcether.com
  packet driver or most DOS/Windows ODI drivers. RFC1201 is included
  automatically as the arc0 device. Please read the ARCnet
  documentation in <file:Documentation/networking/arcnet.txt> for more
  information about using arc0e and arc0s.

CONFIG_ARCNET_1201
  This allows you to use RFC1201 with your ARCnet card via the virtual
  arc0 device.  You need to say Y here to communicate with
  industry-standard RFC1201 implementations, like the arcether.com
  packet driver or most DOS/Windows ODI drivers.  Please read the
  ARCnet documentation in <file:Documentation/networking/arcnet.txt>
  for more information about using arc0.

CONFIG_ARCNET_RAW
  ARCnet "raw mode" packet encapsulation, no soft headers.  Unlikely
  to work unless talking to a copy of the same Linux arcnet driver,
  but perhaps marginally faster in that case.

CONFIG_ARCNET_COM90xx
  This is the chipset driver for the standard COM90xx cards. If you
  have always used the old ARCnet driver without knowing what type of
  card you had, this is probably the one for you.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called com90xx.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt> as well
  as <file:Documentation/networking/net-modules.txt>.

CONFIG_ARCNET_COM90xxIO
  This is the chipset driver for the COM90xx cards, using them in
  IO-mapped mode instead of memory-mapped mode. This is slower than
  the normal driver. Only use it if your card doesn't support shared
  memory.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called com90io.o.  If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt> as well
  as <file:Documentation/networking/net-modules.txt>.

CONFIG_ARCNET_RIM_I
  This is yet another chipset driver for the COM90xx cards, but this
  time only using memory-mapped mode, and no IO ports at all. This
  driver is completely untested, so if you have one of these cards,
  please mail dwmw2@infradead.org, especially if it works!

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you
  want). The module will be called arc-rimi.o.  If you want to compile
  it as a module, say M here and read <file:Documentation/modules.txt>
  as  well as <file:Documentation/networking/net-modules.txt>.

CONFIG_ARCNET_COM20020
  This is the driver for the new COM20020 chipset. It supports such
  things as promiscuous mode, so packet sniffing is possible, and
  extra diagnostic information.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called com20020.o.  If you want to compile it as
  a module, say M here and read <file:Documentation/modules.txt> as
  well as <file:Documentation/networking/net-modules.txt>.
