Hello all, I have some questions on the tcp send routine in net/ipv4/tcp.c: 1) What's the difference/relationship between sk->tp_pinfo.af_tcp->send_head and sk->write_queue. [what purpose do they serve?] 2) What are sk->tp_pinfo.af_tcp->sendmsg_page/sendmsg_off used for? Why is there only one page that's reused in the loop to push the current data? 3) Is skb_shinfo(skb)->nr_frags the number of fragments to be assembled into a tcp segment? If so, what qualifies an sk_buff as a fragment (as opposed to being a full tcp segment). If someone can point me to prior discussions/resources that might help, I'd be grateful...
