Use the kernel pre-defined macro is_broadcast_ether_addr() instead of
doing a memcmp here.

Please avoid use of 'From' tag specially when there is only one
'Signed-off-by' tag and its same.

But the email client isn't putting the correct info in the email header,
so this line is needed.

And if it's redundant, not a problem, git handles it just fine, better
to be safe.

Thanks Greg, for giving the information.
In that case, we can keep the 'From:' tag to be on safe side.
