If a DSA switch supports the related .set_addr operation, the DSA core sets the master's MAC address on the switch. This won't make sense anymore in a multi-CPU ports system, because there won't be a unique master device assigned to a switch tree. Moreover this operation is confusing because it makes the user think that it could be used to program the switch with the MAC address of the CPU/management port such that MAC address learning can be disabled on said port, but in fact, that's not how it is currently used. To fix this, assign a random MAC address at setup time in the mv88e6060 and mv88e6xxx drivers before removing .set_addr completely from DSA. Changes in v3: - include fix for mv88e6060 switch MAC address setter. Changes in v2: - remove .set_addr implementation from drivers and use a random MAC. ==================== Signed-off-by: David S.
