Re-Consider Netlink instead of hand-crafted NS #29

Closed christf closed 6 years ago

christf commented 6 years ago

see #18

It is better to let the kernel do stuff instead of doing it ourselves. We need to make sure though that

we are able to trigger NS at will -> this was not possible with the patchset in #18
no multicast-MACs as target in neighbour-table
src-address must be from unique node-IP

I just re-introduced probing via netlink however it cannot replace the hand-crafted NS. For probing via netlink, it seems the mac address must be known because we operate on a complete neighbour cache entry.

Still probing via netlink is a good addition to l3roamd because that allows us to let the kernel handle status changes, passing only the results to l3roamd.
