I'm curious about the design of stlc45xx/p54 since it is capable of sending/receiving even though power save is enabled. I wonder what blocks of the hw are off when ps is enabled since it is capable of doing the basic operation of Tx/Rx which is the only thing expected from a driver. I seriously doubt if NIC is saving any power at all or the hw design is very novel and interesting.
