Hmm?  There's no Ethernet on the 3530 Beagle.

The hardware configuration on those two boards - the 37xxevm and 
the 3530es3beagle - hasn't changed between the two test runs, AFAIK.

Just to take the Beagle out of the equation, here's a test with the 
37xxevm on 3.11 where it passes the dynamic idle tests:

And here's one on the 37xxevm on 3.16-rc7 where it fails:

I should probably read back those writes to autosuspend_delay_ms, just to 
make sure they are reaching the right destinations.  But you might want to 
confirm that you can see the CORE RET count increasing during dynamic idle 
on your 37xxevm.
