Bond link state is being maintained inconsistently. It is initially set to
up. If the bond interface admin state is set to down, the link state is
set to down. If the bond interface admin state is set to up, the link
state is only set to up if there are active slave interfaces at that point.
If slaves become active at some later time, it does not get updated. Its
next chance to be updated is the next time the bond interface is set to
admin up.
To address this, do not set the link state to up after creating a bond.
Adjust the link state as slave interfaces are attached or detached
based on whether the bond is getting its first active slave or losing
its last one.
Unit test added to verify correct maintenance of link state.

Add a callback to the bond device class which allows a secondary
mac address to be added/deleted.
The desired operation is performed on all the hardware interfaces
which belong to the bond interface. This allows virtual MAC
addresses to be used on bond interfaces without requiring the
hardware interfaces to have promiscuous mode enabled.
When a hardware interface is added or removed from a bond, if there
are any secondary MAC addresses configured on the bond, they are
added or removed from the hardware interface.

Not all interfaces have the same characteristics within the bonding group.
For active-backup mode, we should do our best to select the slave that
performs the best as the primary slave. We already did that by preferring
the slave that is local numa. Sometimes, this is not enough. For example,
when all are local numas, the selection is arbitrary. Some slave interfaces
may have higher speed or better qos than the others. But this is hard to
infer.
One rule does not fit all. So we let the operator to optionally specify the
weight for each slave interface. Our primary slave selection rule is now
1. biggest weight
2. is local numa
3. current primary slave (to avoid churn)
4. lowest sw_if_index (for deterministic behavior)
This selection rule only applies to active-backup mode which only one slave
is used for forwarding traffic until it becomes unreachable. At that time,
the next "best" slave candidate is automatically promoted. The slaves are
sorted according to the preference rule when they are up. So there is no need
to find the next best candidate when the primary slave goes down.
Another good thing about this rule is when the down slave comes back up, it
is selected as the primary slave again unless there is indeed a "better"
slave than this down slave that were added during that period.
To set the weight for the slave interface, do this after the interface is
enslaved
set interface bond <interface-name> weight <value>

Virtual interfaces may be part of the bonding like physical interfaces. The
difference is virtual interfaces may disappear dynamically. As an example,
the following CLI sequence may crash the debug image
create vhost-user socket /tmp/sock1
create bond mode lacp
bond add BondEthernet0 VirtualEthernet0/0/0
delete vhost-user VirtualEhernet0/0/0
Notice the virtual interface is deleted without first doing bond delete.
The proper order is to first remove the slave interface from the bond prior
to deleting the virtual interface as shown below. But we should handle it
anyway.
create vhost-user socket /tmp/sock1
create bond mode lacp
bond add BondEthernet0 VirtualEthernet0/0/0
bond del VirtualEthernet0/0/0 <-----
delete vhost-user VirtualEhernet0/0/0
The fix is to register for VNET_SW_INTERFACE_ADD_DEL_FUNCTION and remove
the slave interface from the bond if the to-be-deleted interface is part of
the bond. We check the interface that it is actually up before we send
the lacp pdu. Up means both hw and sw admin up.

We register callback for VNET_HW_INTERFACE_LINK_UP_DOWN_FUNCTION and
VNET_SW_INTERFACE_ADMIN_UP_DOWN_FUNCTION to add and remove the slave
interface from the bond interface accordingly. For static bonding without
lacp, one would think that it is good enough to put the slave interface into
the ective slave set as soon as it is configured. Wrong, sometimes the slave
interface is configured to be part of the bonding without ever bringing up the
hardware carrier or setting the admin state to up. In that case, we send
traffic to the "dead" slave interface.
The fix is to make sure both the carrier and admin state are up before we put
the slave into the active set for forwarding traffic.

4. update the buffers with the slave sw_if_index
5. Add the buffers to the queues

[VPP-1251]
Problem:
When the bond subinterface is removed, it was observed that we lost the lacp
partner. Show hardware shows rx counter goes up, but show interface does not
for the slave interfaces.
Cause:
We reset the interface promiscuous mode when the bond subinterface is deleted.
This causes dpdk not to accept any packet. Leave the interface in promiscuous
mode fixes the problem.
Other fixes:
There are few places we use hw_if_index as if they are sw_if_index. But they
don't necessarily have the same value. As soon as a subinterface is created,
they start to diverge. The fix is to use the correct API for the hw_if_index
and sw_if_index.

In dpdk based bonding, when the bond interface is configured for l2,
it automatically sets the bond interface to promiscuous mode and sets rx
redirect to ethernet-input. This allows traffic to be bridged to
non compute node facing interface when it is received from the compute
node interface.
For native vpp bonding, we need to do similar things. When the bond interface
is configured for l2, we set the slave interfaces to promiscuous mode
and set rx redirect to ethernet-input because dpdk does not know anything
about the bond interface. Likewise, when a new interface is enslaved, we also
need to do the same thing if the bond interface has already been configured
for l2.

For the debug image, if the interface is removed and the trace was
collected prior to the interface delete, show trace may cause a crash.
This is because vnet_get_sw_interface_name and vnet_get_sup_hw_interface
are not safe if the interface is deleted.
The fix is to use format_vnet_sw_if_index_name if all we need is to
get the interface name in the trace to display. It would show "DELETED"
which is better than a crash.

Add bonding driver to support creation of bond interface which composes of
multiple slave interfaces. The slave interfaces could be physical interfaces,
or just any virtual interfaces. For example, memif interfaces.
The syntax to create a bond interface is
create bond mode <lacp | xor | acitve-backup | broadcast | round-robin>
To enslave an interface to the bond interface,
enslave interface TenGigabitEthernet6/0/0 to BondEthernet0
Please see src/plugins/lacp/lacp_doc.md for more examples and additional
options.
LACP is a control plane protocol which manages and monitors the status of
the slave interfaces. The protocol is part of 802.3ad standard. This patch
implements LACPv1. LACPv2 is not supported.
To enable LACP on the bond interface, specify "mode lacp" when the bond
interface is created. The syntax to enslave a slave interface is the same as
other bonding modes.
