+tcp_autocorking - BOOLEAN
+       Enable TCP auto corking :
+       When applications do consecutive small write()/sendmsg() system calls,
+       we try to coalesce these small writes as much as possible, to lower
+       total amount of sent packets. This is done if at least one prior
+       packet for the flow is waiting in Qdisc queues or device transmit
+       queue. Applications can still use TCP_CORK for optimal behavior
+       when they know how/when to uncork their sockets.
