SOMEIP-SD hidden entries are off

Summary

The following fields are behind the SOME/IP-SD entry instead on it. This means we might read behind the packet!

The following fields are affected:

• someipsd.entry.offerservice
• someipsd.entry.stopofferservice
• someipsd.entry.findservice
• someipsd.entry.subscribeeventgroup
• someipsd.entry.stopsubscribeeventgroup
• someipsd.entry.subscribeeventgroupack
• someipsd.entry.subscribeeventgroupnack

I have a patch prepared and will upload.

Steps to reproduce

Open a trace with SOME/IP-SD and hover over a (hidden) entry item (see list above). It marks the wrong bytes.

What is the current bug behavior?

Offset of these entries is not set to start of the entry.

What is the expected correct behavior?

Offset is at start of entry.
