Subject: MCTP - Socket Queue Behavior
Hello,
Linux implementation of MCTP uses socket for communication with MCTP capable EP's. Socket calls can be made ASYNC by using fcntl. I have a query based on ASYNC properties of the MCTP socket.
1. Does kernel internally maintain queue, for the ASYNC requests?
a. If so, what is the queue depth (can one send multiple requests without waiting for the response and expect reply in order of requests)?
b. Does the Kernel maintain queue per socket connection?
2. Is FASYNC a mechanism for handling asynchronous events associated with a file descriptor and it doesn't provide parallelism for multiple send operation?
Thanks in advance for response.
Regards,
Dharma
