Exactly, only I couldn't convince devctl to reattach the device :')

This is slightly racy ->the interrupt should be teardown first, otherwise it may occurs in the middle
of HW deinitialization or ifc destruction.

Disable and tear down interrupts first in the detach method.

Thanks. Am I right in thinking that the call to ether_ifdetach() adequately protects us from races with dwc_ioctl()?

Meaning, it should not be possible for dwc_ioctl(SIOCGIFMEDIA) to occur while we are deleting the miibus child.
