Description: A value which indicates the set of TCP flags that this entity may potentially offer. The value is a sum of flag bits. This sum initially takes the value zero. Then, for each flag, L is added in the range 1 through 6, for which this node performs transactions, where 2^(L - 1) is added to the sum. Note that values should be calculated accordingly:

Flag functionality 6 urg bit 5 ack bit 4 psh bit 3 rst bit 2 syn bit 1 fin bit For example, it you want to enable urg bit and ack bit, you should set value 48{2^(5-1) + 2^(6-1)}.
