Token that represents fields of DHCPv6 packet.
For example in the expression pkt6.msgtype == 1 this token represents the message type of the DHCPv6 packet. The integer values are placed on the value stack as 4 byte strings.

Gets a value of the specified packet.
The evaluation uses fields that are available in the packet. It does not require any values to be present on the stack.

pkt | - packet from which to extract the fields |
values | - stack of values, 1 result will be pushed |
