Well, the patch did get into the netdev mailing list. I think your direct reply arrived in my mailbox first before I received my own patch through netdev. By the way, I don't see your patch on net-next git. Otherwise, I wouldn't have gone through the trouble of debugging and testing it on my computer. Is there any other repo that I should watch out to avoid this kind of silly situation in the future?
