Description: Display the mask for this rule. This mask corresponds to swACLPktContRuleVarOffsetOffsetIndex4 and swACLPktContRuleVarOffsetData4.
What is swACLPktContRuleVarOffsetMask4?
This stores a 4-byte mask value used by an access control rule to identify which bits in packet data should be examined. Engineers use this when defining packet inspection rules—the mask determines which portions of the packet payload are relevant for matching against the rule's criteria. If set to 0xFF000000 (all bits set in the first byte, zeros in the rest), only the first byte of the packet data is checked against the rule.
