The magic packet flag indicates that the hardware has this
capability.  The MDIO flag indicates that this device's
registers contain active MDIO registers, and thus this
device should not be put to sleep.

Can you explain the MDIO part further, do you mean its the tsec that
has the MDIO registers in its address space or that its actively   
using
MDIO for something?

TSEC1 contains the MDIO registers for both TSEC1 and TSEC2.  Thus,  
TSEC1
cannot be put to sleep if TSEC2 is active (plus, the phy timer would
have to be deactivated).  For now, the simple approach of never  
sleeping
TSEC1 is used.

The PHY timer is part of the PHY Lib.  The PHY Lib has infrastructure  
to support suspend/resume.  Any thoughts on using that?  More in an  
another email.
