Your right I didn't check the driver, but I checked the data sheets which
states that the MAC is loaded upon any reset. If the driver does it it's

There is nothing about my statement that is not true.

I stand by my statement. The core system put's it there, regardless of whether
the OS reloads it or not. I believe we should do the same.
It is an interesting point however, I was unaware that the drivers are loading
the MAC, thank you for pointing it out. Nevertheless, the MAC was already
there, this loading is redundant.
