web commit by martin: Add initial wifi driver state matrix

    1: We currently have 27 wifi drivers in the source tree. A few of them have already been converted for the wifi renewal branch (see [[Wifi renewal on hg]]).
    2: 
    3: | Device| at 			| usbwifi	| converted	| tested	|
    4: |-------|-----------------------|---------------|---------------|---------------|
    5: | an	| pci, pcmcia[1], isapnp | -		| no		| no		|
    6: | ath	| pci[1], cardbus[1]	| -		| no		| no		|
    7: | athn	| pci[1], cardbus, usb	| +/-/?		| no		| no		|
    8: | atu	| usb			| +		| no		| no		|
    9: | atw	| pci, cardbus		| -		| no		| no		|
   10: | awi	| pcmicia		| -		| no		| no		|
   11: | bwfm	| pci, sdmmc[1], usb	| +/-/?		| no		| no		|
   12: | bwi	| pci, cardbus		| -		| no		| no		|
   13: | ipw	| pci			| -		| no		| no		|
   14: | iwi	| pci			| -		| no		| no		|
   15: | iwm	| pci[1]		| -		| yes		| ?		|
   16: | iwn	| pci			| -		| yes		| ?		|
   17: | malo	| pci			| -		| no		| no		|
   18: | otus	| usb			| +		| no		| no		|
   19: | ral	| pci, cardbus, usb	| +/-/?		| no		| no		|
   20: | rsu	| usb			| +		| no		| no		|
   21: | rtw	| pci, cardbus[1]	| -		| no		| no		|
   22: | rtwn	| pci[1]		| -		| yes		| yes		|
   23: | rum	| usb			| +		| no		| no		|
   24: | run	| usb[1]		| +		| no		| no		|
   25: | upgt	| usb			| +		| no		| no		|
   26: | ural	| usb			| +		| no		| no		|
   27: | urtw	| usb			| +		| no		| no		|
   28: | urtwn	| usb[1]		| +		| yes		| yes		|
   29: | wi	| pci, pcmcia[1]	| -		| no		| no		|
   30: | wpi	| pci			| -		| no		| no		|
   31: | zyd	| usb			| +		| no		| no		|
   32: 
   33: [1] = Martin has hardware in testable condition
   34: 
   35: usbwifi = + means: the driver will be converted to usbwifi, which is an easy conversion
   36: 
   37: usbwifi = +/-/? means: at this point it is not clear if the driver (or parts of it) will be able to use usbwifi, the bus frontend vs. backend driver split has to be reviewed to analyze if usbwifi is feaseable/practical and an improvement over manual conversion.
   38: 
   39: Currently the drivers for urtwn(4) and rtwn(4) are converted, the former using usbwifi (see [[Converting USB drivers to usbwifi(9)]]), but it is not clear if there is a unified aproach that lets the usb frontend profit from usbwifi while not stopping the usb and the other frontends from sharing most parts of the driver - this still has to be evaluated.
   40: 
   41: Other drivers sharing similar chipsets accross different busses including usb have not yet been converted, they are marked with +/-/? in the usbwifi column of above table.
