During the submission of the myri10ge driver, some people raised the question of using pages (or any kind of non-contiguous skb) instead of our current 16kB contiguous skb. We are looking at this right now and it is not clear what solution is the best. From what we understand, Linux provides two mostly redundant mechanisms to handle discontinuous skb, the skb->frags and the skb->frag_list, s2io using the latter while e1000 uses the former. Is one or the other recommended? What is the purpose of having them both in the net core?
you really only have one option, to use PAGE_SIZE pages and frags[] w/nr_frags. e1000 tried the frag_list option but that is used by ip reassembly and badly conflicts with driver generated frag_list. - 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
