Re: perm_addr get

Hi all.

From what I understand dev->perm_addr is set only in case the hw has
permanent hw address somewhere written (for example EPROM).

So when I query device which does not have perm_addr set I get:

testt1:~$ ethtool -P team0
Permanent address: 00:00:00:00:00:00

Is this the correct behaviour? Wouldn't it be more correct if
ethtool_get_perm_addr() fails with -ENOENT for something like that?

I don't think we should change the implementation now, as someone might
depend on it.  It's trivial to distinguish this not-a-permanent-address
case.  However the ethtool command output could be improved.
