[f-nsp] Does MLX "show interface" account for Ethernet Preamble and IFG

[GRADY NEELY]

I have a customer who's GigE link utilization hovers around 700-750
meg.  This is during peak hours.  However, they are seeing
pixelization on their IPTV streams, sporadically during peak hours.
So they upgraded the link to 10 GigE and the pixelization problems
subsided.

This sounds like the link may have been peaking over 1Gig, and
measurements were only taken every minute.  My question is this, does
the "Show interface" output (and by extension, the if-mib) account for
the MAC preamble and IFG?
