[PATCH net-next v2 0/4] net: dsa: remove .set_addr
An Ethernet switch may support having a MAC address, which can be used
as the switch's source address in transmitted full-duplex Pause frames.
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 v2:
- remove .set_addr implementation from drivers and use a random MAC.
