Enabling this option allows SO_LINGER processing.
l_onoff = 1,l_linger can set the timeout.
If l_linger=0, When a connection is closed, TCP will terminate the connection.
This means that TCP will discard any data packets stored in the socket send buffer
and send an RST to the peer.
If l_linger!=0,Then closesocket() calls to block the process until
the remaining data packets has been sent or timed out.
