[c-nsp] 6500 SUP720 High Latency and Jitter issues

[Chris Griffin]

Following up here, has anyone noticed that it is often very hard to find 
platform specific release notes for some platforms.  I have found places 
where it has them all up to 12.2, but not any further.  Am I just 
looking in the wrong places?
