Its better to also check phint for outer case, could be implemented as below

If (inner) {
	Shift 
	Hdr = hdrs[0]
}
else {
	Hdr = hdrs[count]
}

hdr-count++

if (phint & IAVF_PHINT_GTPU_EH_DWN)
	VIRTCHNL_SET_PROTO_HDR_TYPE(hdr1, GTPU_EH_PDU_DWN);
else if (phint & IAVF_PHINT_GTPU_EH_UP)
	VIRTCHNL_SET_PROTO_HDR_TYPE(hdr1, GTPU_EH_PDU_UP);
else if (phint & IAVF_PHINT_GTPU_EH)			
	VIRTCHNL_SET_PROTO_HDR_TYPE(hdr1, GTPU_EH);
else if (phint & IAVF_PHINT_GTPU)
	VIRTCHNL_SET_PROTO_HDR_TYPE(hdr1, GTPU_IP);
