Most drivers we got, are not finished and not ready to go to the kernel. Most problematic are Wifi dirivers, till now cardreader drivers too. There is no documentations. Drivers haw lots of dead code with not enough comments. If you stop to work on this, we will need to finish and support then. On other hand i happy to see that realtek wish to collaborate. And it is not easy to get a good reputation. So i do not wont to interrupt you to make a good job. If you wont get the trust back, you will need to start work in the open way. Like it doing Intel, Atheros and other companies. Create a git repository and let people use your code, test it and write patches. Or at least see, that the work is in progress. -- Regards, Oleksij _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
