Right, as are all IPv4 and IPv6 routes too, but for forwarding purposes you
obviously need to program the IP <-> MAC mapping in hardware too. You can see
the usage in 'show plat hard capa pfc'.

Speaking of ND entries, they appear to carry significant new DoS vector which
is rather hard to fix and it appears that not even new gear have given it much
thought at all.
