Hello!

In the gut while analyzing the network, i descovered that Profinet
IO,Connect->ModuleDiffBlock->...->SubmoduleState->IdentInfo is always
Substitute (SU) or Unknown.

I found in
http://anonsvn.wireshark.org/viewvc/trunk/plugins/profinet/packet-dcerpc-pn-io.c?revision=31724&view=markup
that the byte definition may be wrong:

static const value_string pn_io_submodule_state_ident_info[] = {
    { 0x0000, "OK" },
    { 0x0001, "Substitute (SU)" },
    { 0x0001, "Wrong (WR)" },
    { 0x0001, "NoSubmodule (NO)" },
    /*0x0004 - 0x000F reserved */
    { 0, NULL }
};

--------
Doesn't it has to be like this?

static const value_string pn_io_submodule_state_ident_info[] = {
    { 0x0000, "OK" },
    { 0x0001, "Substitute (SU)" },
    { 0x0002, "Wrong (WR)" },
    { 0x0003, "NoSubmodule (NO)" },
    /*0x0004 - 0x000F reserved */
    { 0, NULL }
};

But jeah, i don't have the profinet specification.
