Are there any proofs from the Prophet's Sunnah that confirm a man's 'awrah is what is between the navel and the knee?

A man's 'awrah (private parts that must be covered) is what is between the navel and the knee. The navel and the knee themselves are not part of the 'awrah. The evidence for this comes from several hadiths, including: "Do not expose your thigh," "Cover your thighs, for indeed the thighs are 'awrah," "Did you not know that the thigh is 'awrah?", and "The thigh is 'awrah." Although the chains of narration (asanid) for these hadiths may be weak individually, some strengthen others, and their collective sum elevates them to the rank of authentic (sahih). The majority of jurists have acted upon their implication.
