The default switch config on my units is pass-through. I don't know if
this is true for all units, it may have changed at some point. The
patches in barebox/next make sure that the switch is reset when trying
to bring the network interface up. With this configuration you can use
any of the netleft/netright/netaux connectors to do regular netboot.

For DSA development you will still need a USB network dongle, but for
all development that hasn't to do with the ethernet switch, netbooting
from Barebox works fine with the default configuration.
