Subject: [PATCH net-next v2 1/8] dpaa2-switch: set interface MAC address only on endpoint change
There is no point in updating the MAC address of a switch interface each
time the link state changes, this only needs to happen in case the
endpoint changes (the switch interface is [dis]connected from/to a MAC).
Just move the call to dpaa2_switch_port_set_mac_addr() under
DPSW_IRQ_EVENT_ENDPOINT_CHANGED.

/* We can avoid locking because the "endpoint changed" IRQ
* handler is the only one who changes priv->mac at runtime,
* so we are not racing with anyone.
