Hi, I'm working on a network protocol implementation. A received packet will be queued to a receive queue 'skb_queue_tail()' when the receive function for this protocol id is executed. Then there's a thread which will dequeue one skb at a time to work with it. I've noticed that the skb's dequeued are non-linear 'skb_has_frags()' as my card has the NETIF_F_SG feature set. When I try to skb_linearize() the skb it will be merged to a virual (and maybe even physical) continues memory location, but this will increase the CPU load which is bad at all. My question: Is there any way that I can work with a fragmented/non-linear skb and access the data inside skb_shinfo(skb)->frags[] with a 'struct iovec *iov' so that I'm able to pass the iovec to handler functions which accept them as an argument?
