Typical use case for DSA framework on barebox is a port multiplexer. This means, we mostly have different MAC addresses on each port. To make this work, we need to enable promiscuous mode on the master Ethernet controller.
With this patch, promiscuous mode will be enabled automatically, as soon as at least one switch port is enabled and this mode will be disabled after all switch ports are disabled as well.
