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