bug: ipv4.header.priority.raw with ixia-hw controller

[Carl Montanari]

👋

opening for tracking based on conversation in slack, pasting details here:

given the following metric setup for tracking ipv4 priority raw fields for phb/ecn:

flow.EgressPacket().Add().Ethernet()
tracking := flow.EgressPacket().Add().Ipv4()

tracking.Priority().Raw().MetricTags().Add().SetName(fmt.Sprintf("dst-phb-%d", dscpValue)).SetOffset(0).SetLength(6)

tracking.Priority().Raw().MetricTags().Add().SetName(fmt.Sprintf("dst-ecn-%d", dscpValue)).SetOffset(6).SetLength(2)

I received the following error when running an fp test (dp-1.14 if it matters):

2023-12-19 21:37:47Z span:set_config dur:00:00:05.6460755
  Exception Unable to find field 'ipv4.header.priority.raw' in packet 'ipv4'   at OTGService.ProtocolTemplates.FindField(ProtocolPacket packet, String tclId)

   at OTGService.ConfigService.SetConfig(SetConfigRequest request)
   at OTGService.OtgService.SetConfig(SetConfigRequest request, ServerCallContext context)

with the important part being Exception Unable to find field 'ipv4.header.priority.raw' in packet 'ipv4'

Alakendu Jana mentioned this is/was some issue in OTG-HW side related to ipv4.header.priority.raw . We are working on it

Link to the slack convo.

I should be able to reproduce easily if there's anything else needed, just holler!
