be2net: Fix mac address collision in some configurations
If the device mac address is updated using ndo_set_mac_address(),
while the same mac address is already programmed, the driver does not
detect this condition if its netdev->dev_addr has been changed. The
driver tries to add the same mac address resulting in mac address
collision error. This has been observed in bonding mode-5 configuration.
To fix this, store the mac address configured in HW in the adapter
structure. Use this to compare against the new address being updated
to avoid collision.
