[dpdk-dev] [PATCH] eal: mark version parts API as experimental

[Thomas Monjalon]

Some functions were introduced in DPDK 21.05 to query the version parts
(prefix, year, month, minor, suffix, release) at runtime.
Per guidelines, these new public functions must be marked with
__rte_experimental and ABI versioned as EXPERIMENTAL.

Fixes: 5b637a848195 ("eal: fix querying DPDK version at runtime")
Cc: sta...@dpdk.org
