When there is a bad descriptor, it may in the beginning, in the middle,
or at the end of the batch if the batch has more than 3 descriptors.
When processing a bad descriptor is encountered in the batch, we need to
rollback n_buffers in memif_process_desc(), or the statement in the same
function
memif_add_copy_op (ptd, mb0 + src_off, bytes_to_copy,
dst_off, n_buffers - 1);
is wrong because it picks up the wrong buffer_vec_index of the bad
descriptor while parsing a good descriptor immediately following the
bad descriptor. n_buffers was incremented in the beginning of
while (n_left) loop.
The other problem is we should count the number of bad packets and
reduce ptd->n_packets to get the correct number of packets for subsequent
processing in device_input.
The last fix is to check if n_buffers == 0 in device_input and skip
doing any descriptor copy. This case can happen when all the descriptors
are bad in the batch.

Following the discussion during the review
of b46a4e69e5db18ef792415439d04a0ab22c59386,
remove the redundant ei0. This resulted in realization
that in order for this code to do anything useful,
the ei must be always non-zero, so rewrite the logical
condition for it. Also, make it a conjunction which seems simpler
to understand.

Using the error name makes it less explicit in the packet trace than
the error description when a packet is dropped. Example of the trace
when the TTL is <=1:
01:03:17:015278: drop
ip4-input: time_expired
We should have "ip4 ttl <= 1" instead of "time_expired"

Using "ip neighbor <ip-addr> <mac-addr> static count <count>" to add
static ARP entries will output wrong mac addresses due to lack of
big/little endian conversion. Fix this error by converting mac address
from big endian to little endian before doing the self-increment.

This patch introduces DMA infrastructure into vlib. This is well known
that large amount of memory movements will drain core resource. Nowadays
more and more hardware accelerators were designed out for freeing core
from this burden. Meanwhile some restrictions still remained when
utilizing hardware accelerators, e.g. cross numa throughput will have a
significant drop compared to same node. Normally the number of hardware
accelerator instances will less than cores number, not to mention that
applications number will even beyond the number of cores. Some hardware
may support share virtual address with cores, while others are not.
Here we introduce new DMA infrastructure which can fulfill the
requirements of vpp applications like session and memif and in the
meantime dealing with hardware limitations.
Here is some design backgrounds:
Backend is the abstract of resource which allocated from DMA device
and can do some basic operations like configuration, DMA copy and
result query.
Config is the abstract of application DMA requirement. Application
need to request an unique config index from DMA infrastructure. This
unique config index is associated with backend resource. Two options
cpu fallback and barrier before last can be specified in config.
DMA transfer will be performed by CPU when backend is busy if cpu
fallback option is enabled. DMA transfer callback will be in order
if barrier before last option is enabled.
We constructs all the stuffs that DMA transfer request needed into
DMA batch. It contains the pattern of DMA descriptors and function
pointers for submission and callback. One DMA transfer request need
multiple times batch update and one time batch submission.
DMA backends will assigned to config's workers threads equally. Lock
will be used for thread-safety if same backends assigned to multiple
threads. Backend node will check all the pending requests in worker
thread and do callback with the pointer of DMA batch if transfer
completed. Application can utilize cookie in DMA batch for selves
usage.
DMA architecture:
+----------+ +----------+ +----------+ +----------+
| Config1 | | Config2 | | Config1 | | Config2 |
+----------+ +----------+ +----------+ +----------+
|| || || ||
+-------------------------+ +-------------------------+

Previously, each address maintained an array of 32-bit
reference counts for each of 65K possible ports for each
of 4 NAT protocols. Totalling 1MB per address. Wow.
A close read of the code shows that an "is used" check
precedes each attempted reference count increment.
That means the refcount never actually gets above 1.
That in turn means algorithmically, a bit vector is
sufficient. And one need not be allocated for more
than the highest validated port referenced.
These changes introduce a dynamically sized bit vector
replacing the reference counts, for a maximum of 32K
if all 4 protocols use port 65535. In fact, protocol
OTHER is never used, so at most 24K will be used, and
none of it will be "statically" allocated per address.

We validate each descriptor via memif_validate_desc_data and set
desc_status to non-zero for the corresponding descriptor when
the descriptor is bad. However, desc_status is not propagated back to
xor_status in memif_validate_desc_data which eventually sets
ptd->xor_status.
Not setting ptd->xor_status causes us to treat all descriptors as
"simple". In that case, when we try to copy also the bad descriptors to
the buffers, it results a crash since desc_data is not set to point
to the correct memory in the descriptor.
The fix is to set xor_status in memif_validate_desc_data such that if
there is a bad descriptor in the frame, "is_simple" is set to false and
we have to selectively copy only the good descriptors to the buffers.

Type: fix
After peers roaming support addition, FIB entry tracking stopped
working. For example, it can be observed when an adjacency is stacked on
a FIB entry by the plugin and the FIB entry hasn't got ARP resolution
yet. Once the FIB entry gets ARP resolution, the adjacency is not
re-stacked as it used to. This results in endless ARP requests when a
traffic is sent via the adjacency.
This is broken because the plugin stopped using "midchain delegate" with
peers roaming support addition. The reason is that "midchain delegate"
didn't support stacking on a different FIB entry which is needed when
peer's endpoint changes. Now it is supported there (added in 36892).
With this fix, start using "midchane delegate" again and thus, fix FIB
entry tracking. Also, cover this in tests.

Type: improvement
Currently, once an adjacency is stacked on a FIB entry via
adj_midchain_delegate_stack(), "midchain delegate" is created for the
adjacency and the FIB index is stored there. And all further calls to
adj_midchain_delegate_stack() even passing another FIB index will cause
the function to still use the stored one. In other words, there is
currently no way to stack an adjacency on another FIB index if "midchain
delegate" already exists for it.
Being able to stack on another FIB index is needed for the wireguard
plugin. As per the protocol, peers can roam between different external
endpoints. When an authenticated packet is received and it was sent from
a different endpoint than currently stored, the endpoint needs to be
updated and all futher communication needs to happen with that endpoint.
Thus, the corresponding to that peer adjacencies need to be stacked on
the FIB entry that corresponds to the new endpoint.
With this change, add adj_midchain_delegate_remove() that removes
"midchain delegate". When stacking on another FIB entry is needed,
existing "midchain delegate" can be removed and then, a new one created
with a new FIB index via adj_midchain_delegate_stack().

In several NAT submodules, the number of available ports (0xffff - 1024)
may not be divisible by the number of workers, so port_per_thread is
determined by integer division, which is the floor of the quotient.
Later when a worker index is needed, dividing the port with port_per_thread
may yield an out-of-bound array index into the workers array.
As an example, assume 2 workers are configured, then port_per_thread
will be (0xffff - 1024) / 2, which is 32255. When we compute a worker
index with port 0xffff, we get (0xffff - 1024) / 32255, which is 2,
but since we only have 2 workers, only 0 and 1 are valid indices.
This patch fixes the problem by adding a modulo at the end of the division.
