Description

Updating PCAP to use the new ethernetIP with IPv4 (and Daffodil 3.2.0) is failing.

Please look at https://github.com/DFDLSchemas/PCAP/pull/15

Or you can clone my repo: [e-mail]:mbeckerle/PCAP.git 

Checkout master branch

$ sbt
> testOnly *.TestPCAP – --tests=test_pcap_test_dns

Will reproduce the error.

That test used to be a parserTestCase with roundTrip onePass. However, I have temporarily converted it into an unparserTestCase with roundTrip 'none' to isolate that this bug is only when unparsing.

I think this is a Daffodil 3.2.0 bug. 

However,  I recall somewhere bugs/errors like this being discussed not too long ago.
