Glean Adjacency.
A gleean adjacency represent the need to discover new peers on an attached link. Packets that hit a glean adjacency will generate an ARP/ND packet addessesed to the packet's destination address. Note this is different to an incomplete neighbour adjacency, which does not send ARP/ND requests to the packet's destination address, but instead to the next-hop address of the adjacency itself.
Add (and lock) a new or lock an existing glean adjacency
proto | The protocol for the neighbours that we wish to glean |
sw_if_index | The interface on which to glean |
nh_addr | the address applied to the interface on which to glean. This as the source address in packets when the ARP/ND packet is sent |

adj_glean_update_rewrite
Called by an adjacency provider (an interface type) to configure a glean adj (i.e. and adjacency linked to a connected prefix) to its default behaviour. Other interface types (i.e. 6RD tunnels) can can choose not to use glean behaviour on an adjacency liked to a connected prefix.
