That's a driver issue. If there was to get that information out of the driver (ie, a flag that indicated the cable was unplugged, for instance), then yes, the bond device I have can do that. It's a true master/slave relationship; all of the xmit devices are slaves, and the master does absolutely no xmitting, except to queue a packet to a slave.
