[Kirsher, Jeffrey T] 

We apologize, but last submission you only commented on the first patch and the documentation.

In v1 & v2, you and Jason made comments on the LAN driver implementation (patch 2), which we
addressed all the comments and did not hear any comments to the contrary in v3 until now.  If you
give constructive feedback, will work to fix any issues you find.
