Hi Jiawen Wu

After a quick look at the patches, i'm guessing you are new to
submitting to mainline. So it might even make sense to just post patch
1. Please make it standalone, so most of the txgbe.rst can be removed,
since the driver with just patch 1 has none of the features discussed
in it. We can give you feedback which should help you learn the
process, and what we expect from mainline code. You can then rework
that patch and the rest of your driver from what you have learned,
making further patches easier and faster to review.
