Note:
The numbers listed in the table are not the actual length of these elements in IP packets,
but their length in flow template. DSCP field is one byte in flow template, but six bits in
IP packets. You can judge the total length of template elements using these numbers.
The dscp, exp, ip-precedence and tos fields jointly occupy one byte. One byte is
occupied no matter you define one, two or three of these fields.
