*** error: instruction id '0' fix hw command offsets 68 is too high relative to packet size 60
On trying to create a simple stream, with "IP Address" mode set to "Increment Host", following error is seen on saving the stream, when the stream contents gets validated. This happens only when the frame length is between 64 and 72. Seen with the latest release v4.5.5
Error 22:07:40 *** error: instruction id '0' fix hw command offsets 68 is too high relative to packet size 60
Here is the actual json rpc messages sent and received on creating / validating such a stream

Thanks for following up on this issue. Just wanted to let you know that this issue happens only with version v4.5.5 and version v4.5.4 worked fine
