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 
purely redundancy

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.
