[re]stack a midchain.
'Stacking' is the act of forming parent-child relationships in the data-plane graph. Since function performs recursive loop detection.
adj_index | The index of the midchain to stack |
fei | The FIB entry to stack on |

adj_nbr_midchain_update_rewrite
Midchain Adjacency sub-type.
Update the adjacency's rewrite string. A NULL string implies the rewrite is reset (i.e. when ARP/ND etnry is gone). NB: the adj being updated may be handling traffic in the DP.
