This option controls the delayed acknowledgment algorithm. A socket can receive up to the specified number of TCP segments without generating an ACK. Setting this option to 0 disables delayed acknowledgments.

Note: This option is overridden by EF_DYNAMIC_ACK_THRESH, so both options need to be set to 0 to disable delayed acknowledgments.
