Subject: Bonding MAC address

Hello everyone,

Studying the bonding driver I found that bonding device doesn't choose a new MAC address when the slave which MAC is in use is released.
This is a warning about that - "the permanent HWaddr of slave is still in use by bond - set the HWaddr of slave to a different address to avoid conflicts".
Why not to choose a new MAC for bonding device? Is it intentional or just not implemented?

Best regards,
Igor
