tmnxPtpPortMeanLinkDelayNs

The value of tmnxPtpPortMeanLinkDelayNs contains the estimated one-way
propagation delay on the PTP link, computed using the peer-to-peer
delay mechanism.
              
It represents the 'instantaneous' value of the calculated mean link
delay, using timestamp information from the most recent exchange of
Pdelay_Req, Pdelay_Resp, and possibly Pdelay_Resp_Follow_Up messages.
              
There is no filtering applied to the received messages, and there is
no averaging of this calculation over multiple exchanges of peer delay
messages.
              
The active CPM calculates the mean link delay each time it exchanges
Pdelay_Req, Pdelay_Resp, and possibly Pdelay_Resp_Follow_Up messages
over the link.  The standby CPM does not calculate the mean link
delay, returning a value of 0 for tmnxPtpPortMeanLinkDelayNs.
              
The time that this mean link delay was last calculated is provided in
tmnxPtpPortMeanLinkDelayLastCalc.
              
If the clock has not calculated the mean link delay,
tmnxPtpPortMeanLinkDelayNs returns a value of 0.
              
This corresponds to the 'portDS.meanLinkDelay' data set member defined
in IEEE Std 1588-2019.
