Back in May, some folks at ST-E posted a GPL driver for their CW1200 WLAN chipset. After some back and forth, all communications from its authors abruptly ceased. I've been maintaining and enhancing this driver for my employer, who manufactures modules that utilize the CW1200 chipset. We've supplied it to our customers on top of a custom compat-wireless release, always intending to submit our fixes upstream once ST-E got the driver into the kernel. That never happened, so instead of shouldering the maintainence burden on my own, I've decided to try and take up the torch and get this driver merged again. This driver supports: * 802.11 Client (including WPA) * 802.11 AP (including WPA) * SDIO and SPI host interfaces * 802.11e/WMM/QoS * Has passed WFA testing * Big and Little Endian systems There are known warts with this driver: * Driver targets 3.6.x kernel (haven't tried to build with 3.7/3.8-rc) * IBSS is busted, badly. * Lots of checkpatch warnings (I will fix this up for the next submission) * Lots of magic numbers used (intentionally, I suspect) * Lots of "that seems more complicated than it needs to be" * P2P is untested (by me) * There are some quirks that are only present for compat-wireless's needs, such as the CMD53 workaround and the forced-enabled "generic" SDIO support targetting my employer's SDIO modules. This initial RFC posting is to elicit feedback for the bigger-picture things, rather than worrying about stylistic things like checkpatch failures. There's too much to talk about in advance, so please ask questions, and point out stuff that can be done better. I'll try to correct everything I can. It's worth repeating that I'm not its original author either, but I'm willing to take ownership/maintainership to get this pushed into the mainline -- I'd love nothing more than for ST-E to take an official interest in this driver again. Although I'm maintaining this driver for my employer, this upstream push is being done on my own initiative, on my own time. It may have warts and some questionably complicated ways of doing things, but it does work, and is deployed on tens of thousands of systems in the real world. Anyway. Feedback welcome.
