I don't think I do, just the proper tulips. :/ Ditto. AFAIK, I only have tulips. Patch below looks right to me. Clobbering the skb is certainly wrong.

Dave, Is that something I have to do or the original submitter? Was the "Acked-by" appropriate for me to provide (as maintainer)? I can resubmit with Signed-off-by if that's what is expected. thanks, grant -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Dave, Looks like this patch was never resubmitted. Kyle, can you look at http://lists.openwall.net/netdev/2009/03/27/117 and resubmit the code you had then with my "Acked-by" added please? Or if you don't want to touch it, let me know and I'll resurrect it. thanks, grant -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I got tired of waiting for this resubmission (a month and a half) and just applied the most recent version of the patch to net-2.6. It looked correct to me too. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
