This is from mainline kernel.
commit 06693f305e60202d2795a10bee7fb7da23bc2acc
Merge: 75eaff0 a661b43
Author: Linus Torvalds <torvalds@...ux-foundation.org>
Date:   Wed Jul 31 12:56:18 2013 -0700

    Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
    
    Pull networking fixes from David Miller:

I think you should git pull from mainline kernel.

Thanks
