	Hi,

	This patch also sent to Configure.help maitainers to make sure
they are in sync ;-)

	Jean

ir247_config-2.diff :
-------------------
	o [FEATURE] Remove CONFIG_IRDA_OPTIONS. A menu for only 3 items !
	o [FEATURE] Set various CONFIG_IRDA options default to YES
	o [FEATURE] Advertise more aggressively usage of those options
	  in Configure.help. Too many bug reports of people not using those.
	o [FEATURE] Remove obsolete Configure.help entries

-  is currently empty. This will give a lot of speed improvement when

   Say Y here if you want the IrDA subsystem to write debug information
   to your syslog. You can change the debug level in
   /proc/sys/net/irda/debug .

-IrLAP compression support
-CONFIG_IRDA_COMPRESSION
-  Compression is _not_ part of the IrDA(tm) protocol specification,
-  but it's working great! Linux is the first to try out compression
-  support at the IrLAP layer. This means that you will only benefit
-  from compression if you are running a Linux <-> Linux configuration.
-
-  If you say Y here, you also need to say Y or M to a compression
-  protocol below.
-
-IrLAP Deflate compression
-CONFIG_IRDA_DEFLATE
-  Say Y here if you want to build support for the Deflate compression
-  protocol. The deflate compression (GZIP) is exactly
-  the same as the one used by the PPP protocol.
-
-  If you want to compile this compression support as a module, say M
-  here and read <file:Documentation/modules.txt>.  The module will be
-  called irda_deflate.o.
