may cause problems. A better solution is to have the virtio-user

net/i40e: add option to use latest vector path
For IA, the AVX2 vector path is only recommended to be used on later
platforms (identified by AVX512 support, like SKL etc.) This is because
performance benchmark shows downgrade when running AVX2 vector path on
early platform (BDW/HSW) in some cases. But we still observe perf gain
with some real work loading.
So this patch introduced the new devarg use-latest-supported-vec to
force the driver always selecting the latest supported vec path. Then
apps are able to take AVX2 path on early platforms. And this logic can
be re-used if we will have AVX512 vec path in future.
This patch only affects IA platforms. The selected vec path would be
like the following:
Without devarg/devarg = 0:
Machine vPMD
AVX512F AVX2
AVX2 SSE4.2
SSE4.2 SSE4.2
<SSE4.2 Not Supported
With devarg = 1

mem: rename lock list to fd list
Previously, we were only using lock lists to store per-page lock fd's
because we cannot use modern fcntl() file description locks to lock
parts of the page in single file segments mode.
Now, we will be using this list to store either lock fd's (along with
memseg list fd) in single file segments mode, or per-page fd's (and set
memseg list fd to -1), so rename the list accordingly.

mem: raise maximum fd limit unconditionally
Previously, when we allocated hugepages, we closed the fd's corresponding
to them after we've done our mappings. Since we did mmap(), we didn't
actually lose the reference, but file descriptors used for mmap() do not
count against the fd limit. Since we are going to store all of our fd's,
we will hit the fd limit much more often when using smaller page sizes.
Fix this to raise the fd limit to maximum unconditionally.

eal: do not allow legacy mode with --in-memory mode
In-memory mode was never meant to support legacy mode, because we
cannot sort anonymous pages anyway.

fbarray: fix detach in --no-shconf mode
In noshconf mode, no shared files are created, but we're still trying
to unlink them, resulting in detach/destroy failure even though it
should have succeeded. Fix it by exiting early in noshconf mode.

eal: add strscpy function
The strncpy function has long been deemed unsafe for use,
in favor of strlcpy or snprintf.
While snprintf is standard and strlcpy is still largely available,
they both have issues regarding error checking and performance.
Both will force reading the source buffer past the requested size
if the input is not a proper c-string, and will return the expected
number of bytes copied, meaning that error checking needs to verify
that the number of bytes copied is not superior to the destination
size.
This contributes to awkward code flow, unclear error checking and
potential issues with malformed input.
The function strscpy has been discussed for some time already and
has been made available in the linux kernel[1].
Propose this new function as a safe alternative.
