308	help
309	  Due to Etinc's design choice for its PCISYNC cards, some operations
310	  are only allowed on specific ports of the DSCC4. This option is the
311	  only way for the driver to know that it shouldn't return a success
312	  code for these operations.
313
314	  Please say Y if your card is an Etinc's PCISYNC.

319	help
320	  Various DSCC4 bugs forbid any reliable software reset of the ASIC.
321	  As a replacement, some vendors provide a way to assert the PCI #RST
322	  pin of DSCC4 through the GPIO port of the card. If you choose Y,
323	  the driver will make use of this feature before module removal
324	  (i.e. rmmod). The feature is known to be available on Commtech's
325	  cards. Contact your manufacturer for details.
326
327	  Say Y if your card supports this feature.

336config DLCI
337	tristate "Frame Relay DLCI support"
338	---help---
339	  Support for the Frame Relay protocol.
340
341	  Frame Relay is a fast low-cost way to connect to a remote Internet
342	  access provider or to form a private wide area network. The one
343	  physical line from your box to the local "switch" (i.e. the entry
344	  point to the Frame Relay network, usually at the phone company) can
345	  carry several logical point-to-point connections to other computers
346	  connected to the Frame Relay network. For a general explanation of
347	  the protocol, check out <http://www.mplsforum.org/>.
348
349	  To use frame relay, you need supporting hardware (called FRAD) and
350	  certain programs from the net-tools package as explained in
351	  <file:Documentation/networking/framerelay.txt>.
352
