The byte ignored was already present in the dissecror code and is not related
to this patch. It corresponds to the following code line 909:
offset += 1;//SuboptionDHCP
Presumably a field should be added but I do not have access to the
specification.

I'tested the patch. But I don't think it's correct as one byte from my sample
capture (0x3d) is ignored.

I've checked the latest public available Profinet spec Version 2.0 from 2005,
but I don't find there any details of the DHCP suboptions.
For value 61 DHCP client identifier there's a reference to RFC 2132, and then
only the three exceptions are listed, but I think in Profinet it looks a little
bit different to the one in RFC 2132.
