I don't really want to since this is bonding-specific behavior, and 
we're not performing DAD for the address.  This is just another sysfs 
entry: /sys/class/net/bond*/bonding/num_unsol_na, not a sysctl.

I don't think they are.  In the DAD case we're probing for another node 
that might have the address configured, in the bond failover case we 
want to update the switch quickly so we don't drop packets.
