6fe8ecc10c examples/ip_pipeline: fix IPv6 flow classification
IP Pipeline application with the configuration for Flow Classification
IPV6 did not instantiate.
Parse error in section "PIPELINE1": entry "dma_src_mask" too long

The dma_src_mask check in pipeline_passthrough_parse_args() is wrong.

This fix increases the length of dma_src_mask by 1 for NULL termination
and corrected the validation of dma_src_mask length.
This fix is also propagated to pipeline_fc_parse_args() for key_mask_str
validation.

399b2d4758 examples/ip_pipeline: fix action flow bulk command
Error while executing action flow bulk command
pipeline> p 1 action flow bulk ./config/action.txt
Command "action flow bulk" failed
pipeline>

The flow action entries are added successfully.
But the return value is not computed correctly.
Due to this, the error message appears on CLI.

The return value is computed with rsp->n_flows after rsp pointer is freed.
This fix computes the return value before rsp pointer is freed.

56c9ff8e3e examples/vhost: fix performance
We find significant perfermance drop introduced by below commit,
when vhost example is started with --mergeable 0 and inside vm,
kernel virtio-net driver is used to do ip based forwarding.

The commit, 859b480d5a ("vhost: add guest offload setting"), adds
support for VIRTIO_NET_F_GUEST_TSO4 and VIRTIO_NET_F_GUEST_TSO6,
in vhost lib. But inside vhost example, the way to disable tso only
excludes the direction from virtio to vhost, but not the opposite
direction. When mergeable is disabled, it triggers big_packets path
of virtio-net driver to prepare to receive possible big packets with
size of 64K. Because mergeable is off, for each entry of avail ring,
virtio driver uses 19 desc chained together, with one desc pointing
to header, other 18 desc pointing to 4K-sized pages. But QEMU only
creates 256 desc entries for each vq, which results in that only 13
packets can be received. VM kernel can quickly handle those packets
and go to sleep (HLT).

As QEMU has no option to set the desc entries of a vq, so here,
we disable VIRTIO_NET_F_GUEST_TSO4 and VIRTIO_NET_F_GUEST_TSO6
with VIRTIO_NET_F_HOST_TSO4 and VIRTIO_NET_F_HOST_TSO6 when we
disable tso of vhost example, to avoid VM kernel virtio driver
go into big_packets path.

for zero packet scenario instead of proceeding to

268ca73585 examples/l2fwd-crypto: flush buffers
Crypto operations are enqueued in the crypto devices
when the crypto device buffers are full (MAX_PKT_BURST),
in order to be more efficient.

The problem is that operations might be stuck in those buffers,
if they never get full, and therefore, those operations
will never be performed.

Therefore, it is necessary to have a buffer flush mechanism,
similar to the one used for flush the TX buffers, so eventually,
all packets received are ciphered and sent out.

001a1c0f98 ethdev: get registers width
The ethtool app was allocating too little space for 64-bit
registers which resulted in memory corruption.

Removes hard-coded assumption that device registers
are always 32 bits wide. The rte_eth_dev_get_reg_length
and rte_eth_dev_get_reg_info callbacks did not
provide register size to the app in any way while is
needed to allocate correct number of bytes before
retrieving registers using rte_eth_dev_get_reg.

This commit changes rte_eth_dev_get_reg_info so that
it can be used to retrieve both the number of registers
and their width, and removes the now-redundant
rte_eth_dev_get_reg_length.

a0fd91cefc mempool: rename functions with confusing names
The mempool_count and mempool_free_count behaved contrary to what their
names suggested. The free_count function actually returned the number of
elements that were allocated from the pool, not the number unallocated as
the name implied.

Fix this by introducing two new functions to replace the old ones,
* rte_mempool_avail_count to replace rte_mempool_count
* rte_mempool_in_use_count to replace rte_mempool_free_count

In this patch, the new functions are added, and the old ones are marked
as deprecated. All apps and examples that use the old functions are
updated to use the new functions.

e2a1dd1275 vhost: rename device id variable
I failed to figure out what does "fh" mean here for a long while.
The only guess I could have had is "file handle". So, you get the
point that it's not well named.

I then figured it out that "fh" is derived from the fuse lib, and
my above guess is right. However, device_fh represents a virtio
net device ID. Therefore, here I rename it to vid (Virtio-net device
ID, or Vhost device ID; choose one you prefer) to make it easier for
understanding.

This name (vid) then will be considered to the only interface to
applications. That's another reason to do the rename: it's our
interface, make it more understandable.

3901ed99c2 eal: fix thread naming on FreeBSD
rte_thread_setname was a macro defined only for Linux.
The function rte_thread_setname() can now be used on FreeBSD
as well on Linux.
It is required to build librte_pdump.

The macro was 0 for old glibc. The function is now returning -1.
The related logs are decreased from error to debug level because
it is not an important failure, just a debug inconvenience.

d1082cdede examples: fix duplicated lpm6 name
When starting the ip_fragmentation or ip_reassembly example
on several sockets, it fails.

The name of the lpm6 table is the same on every socket,
resulting in a table creation failure (-EEXIST). The failure
appeared after:
commit f82f705b63 ("lpm: fix allocation of an existing object")

Indeed, before this commit the returned value when the existing
table, which was probably a bug in that case: one table for 2
sockets for lpm6, and one per socket for lpm.

fa667b46f5 examples/ip_pipeline: add core mappings script
This script parses the application configuration file and detects all the
pipelines specified therein, and then, it generates all the possible mappings
of those pipelines on the specified CPU core-list.

As a result, each of the possible pipeline-to-core mappings is saved as
separate output configuration file. For example- if input file is
edge_router_downstream.cfg with 3 pipeline (excluding pipeline 0) and
core-list is “1, 2”, following combinations will be generated-

Pipeline 1        Pipeline 2      Pipeline 3
Core = 1          Core = 1        Core = 2
Core = 1          Core = 2        Core = 1
Core = 2          Core = 1        Core = 1
Core = 2          Core = 2        Core = 1
Core = 2          Core = 1        Core = 2
Core = 1          Core = 2        Core = 2
Core = C1         Core = C1H      Core = C2
Core = C1         Core = C2       Core = C1H
Core = C2         Core = C1       Core = C1H

This script will help users to analyse the performance of application by
evaluating all the generated configuration files with different
pipelines-to-core mappings and obtaining the application configuration file
with best performance.

To run the script, issue the following command;

./pipeline-to-core-mapping.py -i <input_configuration_file> -pc "s<socket-id>c<core-id>"

Some optional arguments are as follows:
  -h, --help            show this help message and exit
  -ht {ON,OFF}, --hyper-thread {ON,OFF}
                        enable/disable hyper threading. default is ON
  -nO, --no-output-file
                        disable output config file generation. Output file
                        generation is enabled by default

5f0c5de435 examples/ip_pipeline: fix false cacheline sharing among threads
In ip_pipeline app, the structure app_thread_data needs to be aligned to
the cache line boundary as threads on different cpu cores are accessing
fields of the app->thread_data and having this structure not aligned on
cacheline boundary leads to false cacheline sharing.
