I am saying this because people are used to and there are scripts out
there using something like:
# ethtool <iface> | grep 'Link'
to react an interface failure.

Then the script is broken. It is asking about hardware state.

I was talking about the team master interface, so it makes sense
to check its 'hardware' state. Just think on 'bond0' interface
with no slaves. It should report Link detected: no.

See bond_release(), what happens if bond->slave_cnt == 0, for instance.
