[PATCH] OSS rme96xx update.

Lingering around for a while. 2.4 forward port.

Documentation/sound/rme96xx

+Beta release of the rme96xx (driver for RME 96XX cards like the 
+"Hammerfall" and the "Hammerfall light") 
+
+Important: The driver module has to be installed on a freshly rebooted system, 
+otherwise the driver might not be able to acquire its buffers.
+
+features:
+
+ - OSS programming interface (i.e. runs with standard OSS soundsoftware) 
+ - OSS/Multichannel interface (OSS multichannel is done by just aquiring
+   more than 2 channels). The driver does not use more than one device 
+   ( yet .. this feature may be implemented later ) 
+ - more than one RME card supported
+
+The driver uses a specific multichannel interface, which I will document
+when the driver gets stable. (take a look at the defines in rme96xx.h,
+which adds blocked multichannel formats i.e instead of 
+lrlrlrlr --> llllrrrr  etc.
+
+Use the "rmectrl" programm to look at the status of the card .. 
+or use xrmectrl, a GUI interface for the ctrl program.
+
+What you can do with the rmectrl program is to set the stereo device for
+OSS emulation (e.g. if you use SPDIF out).
+
+You do:
+
+./ctrl offset 24 24
+
+which makes the stereo device use channels 25 and 26.

+
+copy the first part of the attached source code into rmectrl.c
+and the  second part into xrmectrl (or get the program from
+http://gige.xdv.org/pages/soft/pages/rme)
+
+to compile: gcc -o rmectrl rmectrl.c
