We reserve 40 slots in cpu->copy array prior to copy out to avoid overflowing
the array. However, 40 is not enough for the jumbo frame because desceiptor
buffer len is likely at 1536. Change the reserve to 200 and add ASSERT to avoid
encountering the same problem in the future.

In a rare event, after the vhost protocol message exchange has finished and
the interface had been brought up successfully, the driver MAY still change
its mind about the memory regions by sending new memory maps via
SET_MEM_TABLE. Upon processing SET_MEM_TABLE, VPP invalidates the old memory
regions and the descriptor tables. But it does not re-compute the new
descriptor tables based on the new memory maps. Since VPP does not have the
descriptor tables, it does not read the packets from the vring.
In the normal working case, after SET_MEM_TABLE, the driver follows up with
SET_VRING_ADDRESS which VPP computes the descriptor tables.
The fix is to stash away the descriptor table addresses from
SET_VRING_ADDRESS. Re-compute the new descriptor tables when processing
SET_MEM_TABLE if descriptor table addresses are known.

After the trace is collected and if the interface is then deleted, show
trace may crash for the debug image. This is due to the additional check
in pool_elt_at_index() to make sure that the block is not free.
The fix is to do the check in vhost format trace and return "interface deleted"

Multiple API message handlers call vnet_get_sup_hw_interface(...)
without checking the inbound sw_if_index. This can cause a
pool_elt_at_index ASSERT in a debug image, and major disorder in a
production image.
Given that a number of places are coded as follows, add an
"api_visible_or_null" variant of vnet_get_sup_hw_interface, which
returns NULL given an invalid sw_if_index, or a hidden sw interface:
- hw = vnet_get_sup_hw_interface (vnm, sw_if_index);
+ hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index);
if (hw == NULL || memif_device_class.index != hw->dev_class_index)
return clib_error_return (0, "not a memif interface");
Rename two existing xxx_safe functions -> xxx_or_null to make it
obvious what they return.

Some combinations of new qemu (2.11) and old dpdk (16.10) may
send VHOST_USER_SET_FEATURES at the end of the protocol exchange
which the vhost interface is already declared up and ready.
Unfortunately, the process of VHOST_USER_SET_FEATURES will cause
the interface to go down. Not sure if it is correct or needed.
Because there is no additional messages thereafter, the hardware
interface stays down.
The fix is to check the interface again at the end of processing
VHOST_USER_SET_FEATURES. If it is up and ready, we bring back
the hardware interface.

The fast path almost always has to deal with the real
pointers. Deriving the frame pointer from a frame_index requires a
load of the 32bit frame_index from memory, another 64bit load of the
heap base pointer and some calculations.
Lets store the full pointer instead and do a single 64bit load only.
This helps avoiding problems when the heap is grown and frames are
allocated below vm->heap_aligned_base.

In tap tx routine, virtio_interface_tx_inline, there used to be an
interface spinlock to ensure packets are processed in an orderly fashion
clib_spinlock_lock_if_init (&vif->lockp);
When virtio code was introduced in 19.04, that line is changed to
clib_spinlock_lock_if_init (&vring->lockp);
to accommodate multi-queues.
Unfortunately, althrough the spinlock exists in the vring, it was never
initialized for tap, only for virtio. As a result, many nasty things can
happen when running tap interface in multi-thread environment. Crash is
inevitable.
The fix is to initialize vring->lockp for tap and remove vif->lockp as it
is not used anymore.

Indirect buffers are used to store indirect descriptors
to xmit big packets.
This patch moves the indirect buffer allocation from
interface creation to device node. Now it allocates
or deallocates buffers during tx for chained buffers.

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.

When container is deleted which has tap interface attached,
Linux also delete the tap interface leaving the VPP side of
tap. This patch does a clean up job to remove that VPP side
of tap interface.
To produce the behavior:
In VPP:
create tap
On linux:
sudo ip netns add ns1
sudo ip link set dev tap0 netns ns1
sudo ip netns del ns1

Some API action handlers called vl_msg_ai_send_shmem()
directly. That breaks Unix domain socket API transport.
A couple (bond / vhost) also tried to send a sw_interface_event
directly, but did not send the message to all that had
registred interest. That scheme never worked correctly.
Refactored and improved the interface event code.
