Version 2. Priority / Traffic Class 3. Flow Label Currently, these are not parsed separately and also not set separately in the field bitmap by the flow parser. However, the template treats them separately. As a result, the flow matching doesn't succeed because the bitmaps of parser and the template doesn't match. This patch fixes this problem by parsing the above mentioned fields individually to align with the template.
