23bdcedcd8 mempool: introduce helpers for populate and required size
Introduce new functions that can used by mempool drivers to
calculate required memory size and to populate mempool.

For now, these helpers just replace the *_default() functions
without change. They will be enhanced in next commit.

b291e69423 mempool: introduce function to get mempool page size
In rte_mempool_populate_default(), we determine the page size,
which is needed for calc_size and allocation of memory.

Move this in a function and export it, it will be used in a next
commit.

035ee5bea5 mempool: remove optimistic IOVA-contiguous allocation
The previous commit reduced the amount of required memory when
populating the mempool with non IOVA-contiguous memory.

Since there is no big advantage to have a fully iova-contiguous mempool
if it is not explicitly asked, remove this code, it simplifies the
populate function.

eba11e3646 mempool: reduce wasted space on populate
The size returned by rte_mempool_op_calc_mem_size_default() is aligned
to the specified page size. Therefore, with big pages, the returned size
can be much more that what we really need to populate the mempool.

For instance, populating a mempool that requires 1.1GB of memory with
1GB hugepages can result in allocating 2GB of memory.

This problem is hidden most of the time due to the allocation method of
rte_mempool_populate_default(): when try_iova_contig_mempool=true, it
first tries to allocate an iova contiguous area, without the alignment
constraint. If it fails, it fallbacks to an aligned allocation that does
not require to be iova-contiguous. This can also fallback into several
smaller aligned allocations.

This commit changes rte_mempool_op_calc_mem_size_default() to relax the
alignment constraint to a cache line and to return a smaller size.

Initial version provides two implementations for both IPv4 and IPv6:
dummy (uses RIB as a dataplane) and DIR24_8 (same as current LPM)
Due to proposed design it allows to extend FIB with new algorithms

Add RIB (Routing Information Base) library. This library
implements an IPv4 routing table optimized for control plane
operations. It implements a control plane struct containing routes
in a tree and provides fast add/del operations for routes.
Also it allows to perform fast subtree traversals
(i.e. retrieve existing subroutes for a given prefix).
This structure will be used as a control plane helper structure
for FIB implementation. Also it might be used standalone in other
different places such as bitmaps for example.
Internal implementation is level compressed binary trie.

4da069194e usertools: fix pmdinfo with python 3 and pyelftools>=0.24
Running dpdk-pmdinfo.py on Ubuntu 18.04 (bionic) with python 3 and
pyelftools installed produces no output but no error is reported
neither:

  ~$ python3 usertools/dpdk-pmdinfo.py -r build/app/testpmd
  ~$ echo $?
  0

While with python 2, it works:

  ~# python2 usertools/dpdk-pmdinfo.py -r build/app/testpmd
  {"pci_ids": [], "name": "dpio"}
  {"pci_ids": [], "name": "dpbp"}
  {"pci_ids": [], "name": "dpaa2_qdma"}
  .....

On Ubuntu 18.04, pyelftools is version 0.24. The change log of
pyelftools v0.24 says:

 - Symbol/section names are strings internally now, not bytestrings
   (this may affect API usage in Python 3) (#76).

We cannot guess which version of pyelftools is actually being used. The
elftools.__version__ symbol is not consistent with each distro's package
version. For example, on Ubuntu 16.04 (xenial), the .deb package version
is '0.23-2' but elftools.__version__ contains '0.25'. This is certainly
due to partial backports.

To have a more consistent behaviour of this script across all versions
of python, add the unicode_literals future import so that literal
strings are now always "unicode".

Add 2 utility functions to force a string into bytes or bytes into an
unicode string.

Force pyelftools return values to unicode strings (will do nothing with
recent version of pyelftools).

If elffile.get_section_by_name returns None with a unicode section name,
try with the same one encoded as bytes.

Also, replace all open() calls by io.open() which behaves like the
builtin open in python 3. The only non-binary opened file is
/usr/share/hwdata/pci.ids which is UTF-8 encoded text. Explicitly
specify that encoding.

b4b2f84a59 power: fix socket indicator value
Currently 0 is being used for not connected slot indication.
This is not consistent with linux doc which identifies 0 as valid
(connected) slot, thus modification was done to change it.

0412cfeff9 examples/l3fwd-power: fix Rx interrupt disabling
Interrupt will not be received when disabling RX interrupt without
synchronization mechanism sometimes which leads to wake up issue.
Add spinlock to fix it.

39d21077e5 examples/l3fwd: prefetch the content of the next packet
The cache-misses problem is very serious when the function
lpm_cb_parse_ptype is called to read the content of packets. That is
because the contents of packages previously stored in the cache are
overwritten by the following instructions or variables.
Thus the prefetch order can be used to prefetch the next packet into
the cache to avoid CPU spending too much time on it.

On Octeon TX platform with built-in NIC, 12% performance gain was
measured by running RFC2544 NDR test with l3fwd. Furthermore, the
cache-misses event of the function lpm_cb_parse_ptype was reduced by
20%, and the CPU task-clock of it dropped from 16.49% to 11.3%, based
on the forwarding test for one minute with the 64B packet.
On the dpaa2 platform, no performance improvement nor drop were seen
with this patch by running RFC2544 NDR test with l3fwd.
On the x86 platform, 15.7% performance gain was measured by running
RFC2544 NDR test with l3fwd.

da5350ef29 net: remove ethernet packing and set two-byte alignment
The ether header does not need to be packed since that makes no sense for
structures with only bytes in them, but it should be aligned to a two-byte
boundary to simplify access to it from code. Other packed structures that
use this also need to be updated to take account of the change, either by
removing packing - where it is clearly unneeded - or by explicitly giving
those structures 2-byte alignment also.
