This option was added in bonding version 3.4.0.
all_slaves_active
Specifies that duplicate frames (received on inactive ports) should be
dropped (0) or delivered (1).
Normally, bonding will drop duplicate frames (received on inactive
ports), which is desirable for most users. But there are some times
it is nice to allow duplicate frames to be delivered.
The default value is 0 (drop duplicate frames received on inactive
ports).
arp_interval
Specifies the ARP link monitoring frequency in milliseconds.

determined. See the High Availability section for additional
information. The default value is 0.
min_links
Specifies the minimum number of links that must be active before
asserting carrier. It is similar to the Cisco EtherChannel min-links
feature. This allows setting the minimum number of member ports that
must be up (link-up state) before marking the bond device as up
(carrier on). This is useful for situations where higher level services
such as clustering want to ensure a minimum number of low bandwidth
links are active before switchover. This option only affect 802.3ad
mode.
The default value is 0. This will cause carrier to be asserted (for
802.3ad mode) whenever there is an active aggregator, regardless of the
number of available links in that aggregator. Note that, because an
aggregator cannot be active without at least one available link,
setting this option to 0 or to 1 has the exact same effect.
mode
Specifies one of the bonding policies. The default is
