autocorking_size - INTEGER

Setting SMC auto corking size: SMC auto corking is like TCP auto corking from the application’s perspective of view. 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 CDC and RDMA Write been sent. autocorking_size limits the maximum corked bytes that can be sent to the under device in 1 single sending. If set to 0, the SMC auto corking is disabled. Applications can still use TCP_CORK for optimal behavior when they know how/when to uncork their sockets.
