This patch updates the driver to match the latest Realtek release, and it is an important step in getting the internal code source at Realtek to match the code in the kernel. The primary reason for this is to make it easier for Realtek to maintain the kernel source without requiring an intermediate like me. In this process of merging the two source repositories, there are a lot of changes in both, and this commit is rather large.
