Set the offset at which the 1588 timestamp is written when the output queue is configured as HPE_TX_TIMESTAMP_1STEP. The default value when the queue attribute is set is 14 bytes from the beginning of the frame. This is the normal start of the data payload. This is probably not correct for your application. This is a global setting and affects all output queues configured to inject timestamps.

    HPEHANDLE devhandle,
