Have done sFlow + EAPS on X650s before now with no problems, though the
EAPS rings were relatively small (5ish devices).

As far as I know sFlow sampling is done in hardware. We've been doing
sFlow sampling for a long time and the only issue I remember was sFlow
duplicating each packet it sampled, but that way back (XOS 12.1 or maybe
even XOS 11) and got fixed pretty quickly.
