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.

If the corresponding vpp plugin is absent, return a non-zero
clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The
vat plugin calls dlclose on the vat plugin, and it disappears.
Depending on the plugin configuration, this can reduce the vpp virtual
size by several gigabytes.
Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up
boilerplate vat_plugin_register() implementations. Fixed a number of
non-standard vat_plugin_register methods.

The vlib init function subsystem now supports a mix of procedural and
formally-specified ordering constraints. We should eliminate procedural
knowledge wherever possible.
The following schemes are *roughly* equivalent:
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
clib_error_t *error;
... do some stuff...
if ((error = vlib_call_init_function (init_runs_next)))
return error;
...
}
VLIB_INIT_FUNCTION (init_runs_first);
and
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
... do some stuff...
}
VLIB_INIT_FUNCTION (init_runs_first) =
{
.runs_before = VLIB_INITS("init_runs_next"),
};
The first form will [most likely] call "init_runs_next" on the
spot. The second form means that "init_runs_first" runs before
"init_runs_next," possibly much earlier in the sequence.
Please DO NOT construct sets of init functions where A before B
actually means A *right before* B. It's not necessary - simply combine
A and B - and it leads to hugely annoying debugging exercises when
trying to switch from ad-hoc procedural ordering constraints to formal
ordering constraints.

By definition, passive mode means the node does not start sending lacp pdu until
it first hears from the partner or remote.
- Rename ptx machine's BEGIN state to NO_PERIODIC state.
- Put periodic machine in NO_PERIDOIC state when the interface is enabled for
lacp. ptx machine will transition out of NO_PERIODIC state when the local node
hears from the remote or when the local node is configured for active mode.
- Also add send and receive statistics for debugging.

- hash is great. But it is a bit too slow for the DP. Use direct array indexing
to quickly retrieve the slave interface.
- the algorithm used by flow hash is great. But it is a bit too slow for the DP.
Use l2_hash_hash() extracted from lb_hash.h which ECMP is using. It makes use
of intrinsic crc32 instruction set.
- shortcut modulo arithmetic when the operand is 2**x (where x up to 4) to
avoid division instruction.
- special case for link count == 1 in bond_tx_fn()
- use clib_mem_unaligned to access data for the packet to avoid alignment error
- Fix some typos for packet tracing.
