Experience says otherwise. It's three or four lines of code to attach a page to an SKB frag. The driver needs it's own buffer management and setup code anyways, and no generic facility will replace that. I think your precondition for these changes therefore doesn't really exist. Please, look over all of the drivers that exist already in the tree and build SKBs using page frage from hardware device buffer pools. You have to show us that all of those drivers can make use of your facility. -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
