Enumeration
The state if true, delay sending data < MSS in size unless all prior data has been ACKed. This leads to less in-flight small-data, and less chance for drops, but can harm interactivity. When state is false, sending data < MSS in size is not delayed. When state is auto, the use of Nagle's algorithm is decided based on network conditions. Named after Nagle's algorithm.
