Notes
Arista Keyframes are used to correlate packets to a physical port group.
For instance, any keyframe seen on port 1 associates packets
with that keyframe only with port 1. Likewise, a keyframe seen
on port 2 associates the packets only to port 2, and so on. A
keyframe is unique to a physical port group.

which timestamp to use. The levels are identified starting at the
end of the packet.
