This does not seem to match the latest standards of Ethernet/IP
in "switch(*message_runner)"

Your processing logic is like this:
If "Logical Format" is 01 (LOGICAL_SEGMENT_FORMAT_SIXTEEN_BIT)
Will execute "message_runner += 2;" and then obtain the information
That is, skip the current Logical Segment (one byte) and then skip an additional byte to obtain the data.

But in the latest Ethernert/IP standard (Vol1_3.33 page:1442), whether to skip an extra byte depends on the "Logical Segment
Type ",if"Logical Segment Type " is 111(Extended Logical), there is an extra byte to record "Extended Logical Type", and "Logical
Format" doesn't matter.
