In Linux I2C terminology, a transfer is everything between a START and a STOP. A transfer may consist of multiple messages, connected with REP_START [1]. So, a STOP should be generated after the last message of a transfer or of I2C_M_STOP is set in a message. The latter should be super-rare because mostly you should be able to use multiple transfers with a regular STOP instead.
