The IP protocol number for which this rule applies. If this
object has any value other than 'any' then this rule
takes precedence over any rule that specifies an individual
physical input port, a VLAN or any incoming implicit 802.1p
traffic class rule.
Any attempt to write a rule that indicates a non-default value
for this object together with an individual port value for
extremeQosRuleInPort will be rejected by the agent.
