Failed to create the neighbor entry:

(Pdb++) print (obj, attrs, do_assert)
SAI_OBJECT_TYPE_NEIGHBOR_ENTRY:{"ip_address": "10.1.1.2", "rif_id": "oid:0x600000000001e", "switch_id": "oid:0x21000000000000"} ['SAI_NEIGHBOR_ENTRY_ATTR_DST_MAC_ADDRESS', '00:11:11:11:11:11'] True

>       assert len(status) == 3, f"SAI \"{op[1:]}\" operation failure!"
E       AssertionError: SAI "create" operation failure!

SAI headers neighbor entry definition:

/**
 * @brief Neighbor entry
 */
typedef struct _sai_neighbor_entry_t
{
    /**
     * @brief Switch ID
     *
     * @objects SAI_OBJECT_TYPE_SWITCH
     */
    sai_object_id_t switch_id;

    /**
     * @brief Router interface ID
     *
     * @objects SAI_OBJECT_TYPE_ROUTER_INTERFACE
     */
    sai_object_id_t rif_id;

    /**
     * @brief IP address
     */
    sai_ip_address_t ip_address;

} sai_neighbor_entry_t;

Redis expect the entry key in the following format:

2017-06-14.01:56:16.538038|c|SAI_OBJECT_TYPE_NEIGHBOR_ENTRY:{"ip":"10.1.1.2","rif":"oid:0x600000000001e","switch_id":"oid:0x21000000000000"}|SAI_NEIGHBOR_ENTRY_ATTR_DST_MAC_ADDRESS=00:11:11:11:11:11
