Coming from other network operating systems and also from the logic - we do not "reset" and IP ARP entry, we clear an IP ARP entry.
We also do not reset an IPv6 ND entry, we clear it.
This change also introduces new-style op-mode for IPv6 ND operations rather then directly calling iproute2
Parts should be manually backported to 1.4 sagitta to also provide the new CLI commands but keep the old ones for CLI stability reasons!
