- The ::EslTcp6Listen routine initially places the SOCK_STREAM or\r
- SOCK_SEQPACKET socket into a listen state. When a remote machine\r
- makes a connection to the socket, the TCPv6 network layer calls\r
- ::EslTcp6ListenComplete to complete the connection processing.\r
- EslTcp6ListenComplete manages the connections by placing them in\r
- FIFO order in a queue to be serviced by the application. When the\r
- number of connections exceeds the backlog (ESL_SOCKET::MaxFifoDepth),\r
- the new connection is closed. Eventually, the application indirectly\r
- calls ::EslTcp6Accept to remove the next connection from the queue\r
- and get the associated socket.\r
