>Description:
The epair(4) device does not support being set as a span device in a bridge. ifconfig reports "ifconfig: BRDGADDS epair0a: Device busy" error when trying to set up the device as a span port.

As root:
ifconfig bridge0 create
ifconfig bridge0 up
ifconfig epair0 create
ifconfig bridge0 addm epair0a
ifconfig epair0a up
ifconfig bridge0 span epair0a # <- You will get an error here: "ifconfig: BRDGADDS epair0a: Device busy"
