Well, whole discussion went on linux kernel, and you were the original committer of this patch five years ago. http://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git/commit/?id=bbaffaca4810de1a25e32ecaf836eeaacc7a3d11 So please Paul or David make sure the patch goes in. My only concern is that Paul seems quite busy these days.
