Driver for D-Link DWL-G520+ ??

[Jukka A. Ukkonen]

	Hi!

	Is there anyone writing a driver for a D-Link DWL-G520+ card
	(apparently prism54)?
	The already existing driver for DWL-520+ (prism) does not work
	with the new 54/108 Mbps card. Probably it cannot be modified
	to work at all, because the Ethernet device chips might have
	to be different in these two cards. AFAIK someone said the
	older card had a very slow Ethernet part which just barely made
	it in the 802.11b speeds.

	When checking what the card reports of itself to the pci bus
	"pciconf -lv" gave me originally this...

none0 at pci0:14:0: class=0x028000 card=0x3b041186 chip=0x9066104c rev=0x00 hdr=0x00
    vendor   = 'Texas Instruments (TI)'
    class    = network

	I made the following additions to /usr/share/misc/pci_vendors.
	(A couple of ATI Radeon 9200 entries were missing too.)

	Properly recognising the device id code naturally did not hint
	me to any direction where to start looking for a suitable basis
	or starting point for a new driver or modifying an old existing
	one. Linux people seem to have their own Prism54 team working
	on this hw. They even have a team web site "Linux Driver for
	the 802.11g Prism GT / Prism Duette / Prism Indigo Chipsets".
	How close is that to a good starting point?

	So, if someone is already working with this, it would be nice
	to know. If nobody else has put any effort in this yet, any
	hints helping me grab and modify pieces of existing code would
	be great.


	Cheers,
