This selftest tests for cases where sendfile's 'count' parameter is provided with a size greater than the intended file size. Motivation: When sendfile is provided with 'count' parameter value that is greater than the size of the file, kTLS example fails to send the file correctly. Last chunk of the file is not sent, and the data integrity is compromised. The reason is that the last chunk has MSG_MORE flag set because of which it gets added to pending records, but is not pushed. Note that if user space were to send SSL_shutdown control message, pending records would get flushed and the issue would not happen. So a shutdown control message following sendfile can mask the issue.
