This driver was entered into staging a few cycles ago because there was not time to integrate the Realtek version into the support routines in the kernel. Now that there is an effort to converg the code base from Linux and the Realtek repo, it is time to move this driver. In addition, all the updates included in the 06/28/2014 version of the Realtek drivers are included here. With this change, it will be necessary to delete the staging driver. That will be handled in a separate patch. As it impacts the staging tree, such a patch is sent to a different destination.
