No need to resend, your first patch is still active in patchwork.
David is probably traveling from Ottawa.

vi +100  Documentation/networking/netdev-FAQ.txt

Q: I sent a patch and I'm wondering what happened to it.  How can I tell
   whether it got merged?

A: Start by looking at the main patchworks queue for netdev:

        http://patchwork.ozlabs.org/project/netdev/list/

   The "State" field will tell you exactly where things are at with
   your patch.

Q: The above only says "Under Review".  How can I find out more?

A: Generally speaking, the patches get triaged quickly (in less than 48h).
   So be patient.  Asking the maintainer for status updates on your
   patch is a good way to ensure your patch is ignored or pushed to
   the bottom of the priority list.
