-config ATALK
- tristate "Appletalk protocol support"
- select LLC
- help
- AppleTalk is the protocol that Apple computers can use to communicate
- on a network. If your Linux box is connected to such a network and you
- wish to connect to it, say Y. You will need to use the netatalk package
- so that your Linux box can act as a print and file server for Macs as
- well as access AppleTalk printers. Check out
- <http://www.zettabyte.net/netatalk/> on the WWW for details.
- EtherTalk is the name used for AppleTalk over Ethernet and the
- cheaper and slower LocalTalk is AppleTalk over a proprietary Apple
- network using serial links. EtherTalk and LocalTalk are fully
- supported by Linux.
-
- General information about how to connect Linux, Windows machines and
- Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>. The
- NET3-4-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>, contains valuable
- information as well.
-
- To compile this driver as a module, choose M here: the module will be
- called appletalk. You almost certainly want to compile it as a
- module so you can restart your AppleTalk stack without rebooting
- your machine. I hear that the GNU boycott of Apple is over, so
- even politically correct people are allowed to say Y here.
-
-config DEV_APPLETALK

- depends on ATALK
- help
- AppleTalk is the protocol that Apple computers can use to communicate
- on a network. If your Linux box is connected to such a network, and wish
- to do IP over it, or you have a LocalTalk card and wish to use it to
- connect to the AppleTalk network, say Y.
-
-
-config COPS
- tristate "COPS LocalTalk PC support"
- depends on DEV_APPLETALK && ISA
- depends on NETDEVICES
- select NETDEV_LEGACY_INIT
- help
- This allows you to use COPS AppleTalk cards to connect to LocalTalk
- networks. You also need version 1.3.3 or later of the netatalk
- package. This driver is experimental, which means that it may not
- work. This driver will only work if you choose "AppleTalk DDP"
- networking support, above.
- Please read the file
- <file:Documentation/networking/device_drivers/appletalk/cops.rst>.
-
-config COPS_DAYNA
- bool "Dayna firmware support"
- depends on COPS
- help
- Support COPS compatible cards with Dayna style firmware (Dayna
- DL2000/ Daynatalk/PC (half length), COPS LT-95, Farallon PhoneNET PC
- III, Farallon PhoneNET PC II).
-
-config COPS_TANGENT
- bool "Tangent firmware support"
- depends on COPS
- help
- Support COPS compatible cards with Tangent style firmware (Tangent
- ATB_II, Novell NL-1000, Daystar Digital LT-200.
-
-config IPDDP
- tristate "Appletalk-IP driver support"
- depends on DEV_APPLETALK && ATALK
- help
- This allows IP networking for users who only have AppleTalk
- networking available. This feature is experimental. With this
- driver, you can encapsulate IP inside AppleTalk (e.g. if your Linux
- box is stuck on an AppleTalk only network) or decapsulate (e.g. if
- you want your Linux box to act as an Internet gateway for a zoo of
- AppleTalk connected Macs). Please see the file
- <file:Documentation/networking/ipddp.rst> for more information.
-
- If you say Y here, the AppleTalk-IP support will be compiled into
- the kernel. In this case, you can either use encapsulation or
- decapsulation, but not both. With the following two questions, you
- decide which one you want.
-
- To compile the AppleTalk-IP support as a module, choose M here: the
- module will be called ipddp.
- In this case, you will be able to use both encapsulation and
- decapsulation simultaneously, by loading two copies of the module
- and specifying different values for the module option ipddp_mode.
-
-config IPDDP_ENCAP
- bool "IP to Appletalk-IP Encapsulation support"
- depends on IPDDP
- help
- If you say Y here, the AppleTalk-IP code will be able to encapsulate
- IP packets inside AppleTalk frames; this is useful if your Linux box
- is stuck on an AppleTalk network (which hopefully contains a
- decapsulator somewhere). Please see
- <file:Documentation/networking/ipddp.rst> for more information.
