It can be done with netgraph and either the nc_fec or ng_one2many
nodes. ng_one2many is documented, but does not do link failure
detection and always uses roundrobin delivery (which may result in
out-of-order packets).  ng_fec's output hash can be either on MAC
address or IP address.  Neither node sends LACP or PAgP packets so you
must manually configure the switch at the other end.  The only
documentation for ng_fec is in the orignal maililnglist announcement at
