I already responded to this a few emails back.
My suggestion then was:
Pick between a timer and a number of packets X transmitted, whichever
comes first. [In e1000 for example, the opening strategy is every time
32 packets get transmitted, you open up]. 
In the case of wireless, pick two numbers XHH and XHL with XHL < XHH.
The timers would be similar in nature (THH > THL). All these variables
are only valid if you shutdown the ring. 
So in the case HL shuts down the ring, you fire THL. If either XHL
packets are transmitted or THL expires, you netif_wake.
Did that make sense?

BTW, this thread is going back and forth on the same recycled
arguements. As an example, i have responded to this specific question.
Can we drop the discussion?
