BeagleBone build 3.8.13 kernel with rt_preempt patch: No network, no eth0

I’ve been having problems with i2c and I think that this patch will fix it. https://github.com/RobertCNelson/linux-dev/blob/am33x-v3.8/patches/i2c/0002-Bone-DTS-working-i2c2-i2c3-in-the-tree.patch
How do I apply this patch to my BBB? I am new to this and would appreciate the help!

In the folder linux-dev, you have the folder patches, you put it there. Then, you need to add the patch in the file patch.sh
