Hi,
I just read David S. Miller's skb redundancy page and in it he seems to suggest taking an approach similar to that of BSD's mbufs to reduce the skb's size. I was going to do some janitor work on the network stack and I thought that maybe I could start by adding a tag list to the skb similar to BSD's mbuf tags and change the code to store its private variables in tags rather than in skb->cb. That should save 40 bytes per skb and maybe later the tc and nf related variables could go in tags too. The transition shouldn't be hard for the most part, many users of skb->cb use macros like FRAG_CB(skb) so I could redefine those macros to search the tag-list for the appropriate tag and return its contents. Is this approach acceptable or is there a consensus on another approach? - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
