ptp_analyzer not reporting correct

[dcrearer]

It appear that the for loop that extracts the time stamp from the ptp messages are dependent on the source port. Example if int(pkt.udp.port) == PTP_PORT_1 and int(pkt.ptp.v2_messageid) == MSG_ID_SYNC_MSG:

The if statement evaluates to false if the UDP source port is not 319.
Sine this is a sync message should the if statement evaluate the destination port?

I just opened IEEE 1588, and Annex E says:
E.2 UDP port numbers
"The UDP destination port value of an event message shall be 319." Will you propose a pull request?

Note, The PTP script is just a small demonstration. In a good implementation, one would like to a state machine to keep track of the PTP communication.
