[c-nsp] A9K-4HG-FLEX - experiences with SFP+ modules in SFP28 ports?

[Brian Knight]

Hi Dmitry, Steinar,

Thanks for your responses. This gives me confidence that we don't need 
to stock dual-rate SFP28 10G/25G optics, and our operations staff don't 
need to account for a new type of optic.

Thanks also for mentioning the resources explaining the port groups. 
Found those a few months back when researching the card for suitability 
in the network. That Youtube video was particularly helpful. We plan to 
configure some 10x10G groups, hence the question.
