    thanks Julian, but i prefer to do it myself,
    cause i want to understand how the hell netgraph works... =)
     
    btw, i think i did the converion and it was quite straightforward,
    but i've still a little problem that i didn't have in 5.x:

    if i try to unload my module, change the internals, compile
    and use it again, it fails! =P

    I think it's a problem in the shutdown/disconnect
    part of my work, cause this is what i get:

    ngctl mkpeer rl0: tee lower right
    ngctl: send msg: File exists

    actually tee is my own node, i didn't yet change the name
    to classifier but it's my node.

    And while you are listening, i can show u something else... =)

    I have NETGRAPH in my kernel, and this is what i get when i
    try to load ng_ether the first time:

    [root@newluxor root]# kldload ng_ether
    module_register: module netgraph already exists!
    linker_file_sysinit "netgraph.ko" failed to register! 17
    kldload: can't load ng_ether: Exec format error
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    it fails to load the node...

    [root@newluxor root]# kldload ng_ether

    while the second time it works... =O

    [root@newluxor root]# kldunload ng_ether
    kldunload: can't unload file: Device busy

    and if i try to unload it, it always says that it's busy:
    i think this is due to the inability to delete
    an interface, isn't it?

    nothing really nasty, but maybe you didn't know... =)

    thank you & bye.
