well that was the intention but... The point is - as device is emulated, (nearly) everything is doable,
and the only tradeoff to consider, is how far will we go with that emulation. IOW, PHYlib could be tricked
to "do the right thing", and I thought about adding module flexibility...
But thinking more about it, it seems that BSP-code-phy-creation just sucks less and is clear enough yet flexible.
