352f63de75 gnrc/ipv6: notify L3_ROUTING of discovered/ unreachable nodes 2025-12-09 16:03:59 +01:00

8746281d9d gnrc/ipv6: modify nib nc on l2 connection event 
If a new L2 connection was established, the node should be inserted in
the neighbor cache.
For 6LN nodes, NIB will never start the usual neighbor discovery process
because it can directly resolve the link-layer address from the IPv6
address. Thus we have to manually add such nodes to the NC by building
the IPv6 address from the L2 address.

If a L2 connection closed, the node is removed again from the NC.
