I've been working since two month on this driver, i've understand most part of the chip, but enable to receive any frame. This week-end, i've implemented code to be able to send frames, without luck. My laptop was not able to see any frames sent by my card. And yesterday, i'see that i've forgot to uncomment a code to setup the ring buffer for transmit, and receive data. I uncomment it, and fix writing into the wrong memory, and i receive 96 frames (96 is the number of internal buffer).
The next step will be to analyse this frame (i already know this is a 802.11 frame with a padding). A lot of works remains, but i've great chance to produce a driver for Christmas's.
