Steps to reproduce
------------------

1, Build latest dpdk(dpdk26.07rc1)
cd dpdk
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Dlibdir=lib -Dc_args=-DRTE_BUILD_SHARED_LIB
--default-library=shared x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
rm -rf /root/tmp/dpdk_share_lib /root/shared_lib_dpdk
DESTDIR=/root/tmp/dpdk_share_lib ninja -C x86_64-native-linuxapp-gcc -j 110
install
mv /root/tmp/dpdk_share_lib/usr/local/lib /root/shared_lib_dpdk
cat /root/.bashrc | grep LD_LIBRARY_PATH
sed -i 's#export LD_LIBRARY_PATH=.*#export
LD_LIBRARY_PATH=/root/shared_lib_dpdk#g' /root/.bashrc

2, copy LTS(dpdk25.11) dpdk_abi.tar.gz and build LTS dpdk
tar zxf /tmp/dpdk_abi.tar.gz -C ~
cd ~/dpdk/
rm -rf x86_64-native-linuxapp-gcc
CC=gcc meson -Dlibdir=lib -Dc_args=-DRTE_BUILD_SHARED_LIB
--default-library=shared x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
rm -rf x86_64-native-linuxapp-gcc/lib
rm -rf x86_64-native-linuxapp-gcc/drivers

3, start testpmd
root@icx-jy-abi-d81:~/dpdk# x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-4
-n 4 -a 0000:31:00.0 --file-prefix=dpdk_14651_20260325102153  -d
/root/shared_lib_dpdk   -- -i

Show the output from the previous commands.

    ethdev: promote flow metadata API to stable

    Following experimental symbols related to flow metadata
    were added in v19.11:

    - rte_flow_dynf_metadata_register
    - rte_flow_dynf_metadata_offs
    - rte_flow_dynf_metadata_mask

    Type of rte_flow_dynf_metadata_offs was changed from int to int32_t
    in v20.05 release.
    There were no changes to these symbols since then.

    This patch promotes these symbols and removes __rte_experimental
    from the following inline functions:

    - rte_flow_dynf_metadata_avail
    - rte_flow_dynf_metadata_get
    - rte_flow_dynf_metadata_set

    All these symbols and functions will be used by netdev-doca
    backend in Open vSwitch [1].
    Stabilizing these symbols is required by current OVS policy
    to remove the need for ALLOW_EXPERIMENTAL_API [2].
