I see in a Wireshark trace "TCP payload (1460 bytes)" and "TCP segment data (1398 bytes). (This is from the first TCP segment corresponding to a TLS "Server hello" and there are three other segments that follow this.)
Could someone please help me? (Note: I also asked at https://stackoverflow.com/questions/50808140/wireshark-what-is-the-difference-between-tcp-payload-and-tcp-segment-data)
