TX/RX PTP Message Count/Rate
Gives the transmitted/received count and average rate for each PTP
message, and the total count for all messages.
Note: In the case where messages are lost while the Receipt Timeout is set to a
large value (slow communication), the last valid recorded rate value will
be preceded with “<” to indicate that the reception rate is not stable. This
applies to Delay Resp, Announce, Sync, and Follow UP.
Note: When the rate is above 150 message/s, “> 150” is displayed.

a. The rate value corresponds to an average rate because these messages are only
transmitted/received when negotiating or renewing the lease with the Grand Master
clock. If the connection with the Grand Master Clock was already established when the
test is started, the 0 value is displayed. However, the value becomes available with the
next lease renewal which happens every 150 seconds.
