Subject: [PATCH 5.10 219/221] Revert "net: bonding: fix error return code of bond_neigh_init()"
From: David S. Miller <davem@...emloft.net>
commit 080bfa1e6d928a5d1f185cc44e5f3c251df06df5 upstream.
This reverts commit 2055a99da8a253a357bdfd359b3338ef3375a26c.
This change rejects legitimate configurations.
A slave doesn't need to exist nor implement ndo_slave_setup.
