[c-nsp] What is the lowest latency switch?

[Chris Evans]

The qfx3500 looks great on paper. However there are a lot of features that
aren't supported at FCS.. One big one such as Layer 3 functionality, its not
supported until Q3.

The QFX3500 also uses the same merchant silicon that the Nexus 3K uses..
