The __rte_experimental macro tags a given exported function as being part of
the EXPERIMENTAL api. Use of this tag will cause any caller of the
function (that isn't removed by dead code elimination) to emit a warning
that the user is making use of an API whos stabilty isn't guaranteed.
It also places the function in the .text.experimental section, which is
used to validate the tag against the corresponding library version map
Signed-off-by: Neil Horman <nhorman@tuxdriver.com>
This tools reads the given version map for a directory, and checks to
ensure that, for each symbol listed in the export list, the corresponding
definition is tagged as __rte_experimental, erroring out if its not. In this
way, we can ensure that the EXPERIMENTAL api is kept in sync with the tags

This patch adds a call to the newly introduced cleanup()
function just before quitting the app.
Adding this function call before quitting from a secondary processes
is important, as otherwise it will leak hugepage memory. For a secondary

to become depleted and stop a secondary process from starting.

This commit adds a new function rte_eal_cleanup().
The function serves as a hook to allow DPDK to release
internal resources (e.g.: hugepage allocations).
This function allows DPDK to become more like an ordinary
library, where the library context itself can be initialized
and cleaned up by the application.
The rte_exit() and rte_panic() functions must be considered,
particularly if they should call rte_eal_cleanup() to release any
resources or not. This patch adds the cleanup to rte_exit(),
but does not clean up on rte_panic(). The reason to not clean
up on panicing is that the developer may wish to inspect the
exact internal state of EAL and hugepages.

This patch is to support C11 memory model barrier in librte_ring.
There are 2 barrier implementation options in librte_ring (suggested
by Jerin).
1. use rte_smp_rmb
2. use load_acquire/store_release(refer to [1]).
The reason why providing 2 options is the performance benchmark
difference in different arm machines, refer to [2].
CONFIG_RTE_RING_USE_C11_MEM_MODEL is provided, and by default it is "n"
on any architectures and only "y" on arm64 so far.

When using dynamic tokens, the result buffer contains pointers to some
location inside the result buffer. When the content of the temporary
buffer is copied in the final one, these pointers still point to the
temporary buffer.
This works until the temporary buffer is kept intact, but the next
commit introduces a memset() that breaks this assumption.
This commit keeps the successfully parsed buffers, and ensures that the
pointers point to the valid location, by using temp buffer for following
parsing.
