ZMQ_TCP_RECV_BUFFER: Size of the TCP receive buffer
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The 'ZMQ_RECV_BUFFER' specifies the maximum number of bytes which can
be received by an individual syscall to receive data from the TCP
socket. The buffer size is specified as an integer number from 0 (very small)
to 10 (very large). The default value is 3.
The 'ZMQ_TCP_RECV_BUFFER' specifies the maximum number of bytes which can
be received by an individual syscall to receive data from the TCP socket.
The default value is 8192.
