Specifies the upper protocol number in decimal. Upper
protocols include TCP, UDP, ICMP, and IGMP.

Specifies the upper or lower limit of the IP user data length
(value of total packet length minus header length in bytes).
Table 1-57 shows the relationships between such upper and
lower limits and the resulting user data length. In this table,
"A" indicates the packet length excluding the header length,
and "B" indicates the IP user data length.
