I am quite in doubt if the driver will be able to overwrite a blackhole
entry added by userspace as the replace action must be to delete and
then add the replacement afaics, but a NEWNEIGH event using
port_fdb_add() will not succeed with that using the ops I use now.
Otherwise it has be all with port_fb_add() with new lists keeping the
userspace added blackhole fdb entries.
