one implication of this is that, when this is in use, the NIC cannot be
part of a L2 aggregation (because the upstream switch will load-spread
some of the management traffic flows to other ports in the aggregation).
And using it with other L2/L3 redundancy technologies (such as IPMP and
OSPF-MP) is going to be tricky (the shared management IP address must
not be seen as reachable via other NICs).
