>    etherdevice: introduce help function eth_zero_addr()
>    
>    a lot of code has either the memset or an inefficient copy
>    from a static array that contains the all-zeros Ethernet address.
>    Introduce help function eth_zero_addr() to fill an address with
>    all zeros, making the code clearer and allowing us to get rid of
>    some constant arrays.
