Multicasting
0 : disable Multicasting
1 : enable Multicasting

Use No Delayed ACK
0 : Disable No Delayed ACK option
1 : Enable No Delayed ACK option,
It is applied only in case of TCP. If this bit is set as ‘1’, ACK packet is transmitted
whenever receiving data packet from the peer. If this bit is cleared to ‘0’, ACK packet
is transmitted according to internal Timeout mechanism.
