[c-nsp] How important is the HW revision of a module?

Hi,

> How concerned should I be about the HW and FW revisions?  2.2 to 4.3 seems pretty far apart.

I think the Hw isnt a problem - its usually a slightly different PCB layout,
new ASIC, different capacitors etc.  if there was a hardware fault then
that would be VERY interesting for customers with the affected Hw.

however, the Fw can be an issue - especially with regards to inter-op and bugs - I would advise
upgrading that linecard to the latest release (if you have access!)
