Set TCP accept mail box size. Generally bigger value means supporting larger backlogs
but more memory. The recommended value is 6, but applications can set it to a lower value
if listening servers are meant to have a smaller backlog.
TCP accept mail box is a per socket mail box, when the application listens for connections
with a given listening TCP socket. If the mailbox is full, LWIP will send a RST packet and
the client will fail to connect.
