With commit c1f897ce18 ("bonding: set default miimon value for non-arp
modes if not set") the miimon default was changed from zero to 100 if
arp_interval is also zero. Document this fact in bonding.rst.

tlb_dynamic_lb bonding option is compatible with balance-tlb and balance-alb
modes. In order to be consistent with other option documentation, it should
mention both modes not only balance-tlb.

Add per port priority support for bonding active slave re-selection during
failover. A higher number means higher priority in selection. The primary
slave still has the highest priority. This option also follows the
primary_reselect rules.
This option could only be configured via netlink.

This patch add a new bonding option ns_ip6_target, which correspond
to the arp_ip_target. With this we set IPv6 targets and send IPv6 NS
request to determine the health of the link.
For other related options like the validation, we still use
arp_validate, and will change to ns_validate later.
Note: the sysfs configuration support was removed based on

When 802.3ad bond mode is configured the ad_actor_system option is set to
"00:00:00:00:00:00". But when trying to set the all-zeroes MAC as actors'
system address it was failing with EINVAL.
An all-zeroes ethernet address is valid, only multicast addresses are not
valid values.

Currently, we use hard code number to verify if we are in the
arp_interval timeslice. But some user may want to reduce/extend
the verify timeslice. With the similar team option 'missed_max'
the uers could change that number based on their own environment.

Add an option lacp_active, which is similar with team's runner.active.
This option specifies whether to send LACPDU frames periodically. If set
on, the LACPDU frames are sent along with the configured lacp_rate
setting. If set off, the LACPDU frames acts as "speak when spoken to".
Note, the LACPDU state frames still will be sent when init or unbind port.

This comes from an end-user request, where they're running multiple VMs on
hosts with bonded interfaces connected to some interest switch topologies,
where 802.3ad isn't an option. They're currently running a proprietary
solution that effectively achieves load-balancing of VMs and bandwidth
utilization improvements with a similar form of transmission algorithm.
Basically, each VM has it's own vlan, so it always sends its traffic out
the same interface, unless that interface fails. Traffic gets split
between the interfaces, maintaining a consistent path, with failover still
available if an interface goes down.
Unlike bond_eth_hash(), this hash function is using the full source MAC
address instead of just the last byte, as there are so few components to
the hash, and in the no-vlan case, we would be returning just the last
byte of the source MAC as the hash value. It's entirely possible to have
two NICs in a bond with the same last byte of their MAC, but not the same
MAC, so this adjustment should guarantee distinct hashes in all cases.
This has been rudimetarily tested to provide similar results to the
proprietary solution it is aiming to replace. A patch for iproute2 is also
posted, to properly support the new mode there as well.
