The solution is to record the port of the VF (instead of a pointer)

From previous patch description: "to improve performance on PPC64,
use light weight sync instruction instead of sync instruction."
Excerpt from IBM doc [1], section "Memory barrier instructions":
"The second form of the sync instruction is light-weight sync,
or lwsync.
This form is used to control ordering for storage accesses to system
memory only. It does not create a memory barrier for accesses to
device memory."
This patch removes the use of lwsync, so calls to rte_wmb() and
rte_rmb() will provide correct memory barrier to ensure order of
accesses to system memory and device memory.

Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com>
Previously, when using non-exact allocation, we were requesting
N pages to be allocated, but allowed the memory subsystem to
allocate less than requested. However, we were still expecting
to see N contigous free pages in the memseg list.
This presents a problem because there is no way to try and
allocate as many pages as possible, even if there isn't
enough contiguous free entries in the list.
To address this, use the new "find biggest" fbarray API's when
allocating non-exact number of pages. This way, we will first
check how many entries in the list are actually available, and
then try to allocate up to that number.

Currently, there are numerous reliability issues with fbarray,
such as:
- There is no way to prevent attaching to overlapping memory
areas
- There is no way to prevent double-detach
- Failed destroy leaves fbarray in an invalid state (fbarray
itself is valid, but its backing memory area is already
detached)
In addition, on FreeBSD, doing mmap() on a file descriptor
does not keep the lock, so we also need to store the fd
in order to keep the lock.
This patch improves upon fbarray to address both of these
issues by adding an internal tailq to track allocated areas
and their respective file descriptors.

In weak memory models, like arm64, reading the prod.tail may get
reordered after reading the ring slots, which corrupts the ring and
stale data is observed.
This issue was reported by NXP on 8-A72 DPAA2 board. The problem is most
likely caused by missing the acquire semantics when reading
prod.tail (in SC dequeue) which makes it possible to read a
stale value from the ring slots.
For MP (and MC) case, rte_atomic32_cmpset() already provides the required
ordering. For SP case, the control depependency between if-statement (which
depends on the read of r->cons.tail) and the later stores to the ring slots
make RMB unnecessary. About the control dependency, read more at:
https://www.cl.cam.ac.uk/~pes20/ppc-supplemental/test7.pdf
This patch is adding the required read barrier to prevent reading the ring
slots get reordered before reading prod.tail for SC case.

Since we have the version number in a separate file at the root level,
we should not need to duplicate this in rte_version.h too. Best
approach here is to move the macros for specifying the year/month/etc.
parts from the version header file to the build config file - leaving
the other utility macros for e.g. printing the version string, where they
are.
For "make", this is done by having a little bit of awk parse the version
file and pass the results through to the preprocessor for the config
generation stage.
For "meson", this is done by parsing the version and adding it to the
standard dpdk_conf object.
In both cases, we need to append a large number - in this case "99",
previously 16 in original code - to the version number when we want to do
version number comparisons. Without this, the release version e.g. 19.05.0
will compare as less than it's RC's e.g. 19.05.0-rc4. With it, the
comparison is correct as "19.05.0.99 > 19.05.0-rc4.99".
