The parameters are as follows:
ad_select
Specifies the 802.3ad aggregation selection logic to use. The
possible values and their effects are:
stable or 0
The active aggregator is chosen by largest aggregate
bandwidth.
Reselection of the active aggregator occurs only when all
slaves of the active aggregator are down or the active
aggregator has no slaves.
This is the default value.
bandwidth or 1
The active aggregator is chosen by largest aggregate
bandwidth. Reselection occurs if:
- A slave is added to or removed from the bond
- Any slave's link state changes
- Any slave's 802.3ad association state changes
- The bond's adminstrative state changes to up
count or 2
The active aggregator is chosen by the largest number of
ports (slaves). Reselection occurs as described under the
"bandwidth" setting, above.
The bandwidth and count selection policies permit failover of
802.3ad aggregations when partial failure of the active aggregator
occurs. This keeps the aggregator with the highest availability
(either in bandwidth or in number of ports) active at all times.
This option was added in bonding version 3.4.0.
arp_interval
Specifies the ARP link monitoring frequency in milliseconds.

num_unsol_na
Specifies the number of unsolicited IPv6 Neighbor Advertisements
to be issued after a failover event. One unsolicited NA is issued
immediately after the failover.
The valid range is 0 - 255; the default value is 1. This option
