Hi, I got several questions about the structures in TCP/IP implementation in Linux kernel version 2.4.2. 1. In freebsd, there is structure called "tun_softc" which controls the interface property of the tunnel network. In Linux, i just found structure of "net_device" doing same thing for all the network device. I am wondering if there is some structures which directly controls the tunnel network instead of the general network device? E.g. I want to get the info whether the interface has packet in its sending queue. 2. I am wondering in linux whether ALL the sending or receiving tcp "sock" are linked together as a link list? And how can I find the first element in the list? Please cc the reply to zhuyingj@comp.nus.edu.sg and thanks a lot for the help.
