Betreff: Re: Realtek Otto PHY hardware polling

quoted

Basically there is no need to disable/enable polling for an access. 
We are running OpenWrt with polling enabled all the time without 
major issues.

- It is only used for special functions (fiber, EEE, hard reset, SerDes
  calibration).

One obvious question is, why are these special? Hard reset i can
understand, you need to know the reset is complete before trying to
use the registers. But the others?

Either we need some documentation from Realtek, or we need to reverse
engineer the hardware to understand what it does.

Just out of curiosity I ordered a logic analyzer. Lets see
if it tells us more.
