[Environment]
DPDK version: 
dpdk 23.03 baf13c3135d0c59
Other software versions: N/A.
OS: Ubuntu20.04.5/5.15.0-57-generic
Compiler: clang version 10.0.0-4ubuntu1
Hardware platform: Intel(R) Xeon(R) Platinum 8280M CPU @ 2.70GHz
NIC hardware: I40E_10G-10G_BASE_T_X722
NIC driver: i40e-2.22.8
NIC firmware: 6.20 0x80003d3e 1.2935.0

[Test Setup]
Steps to reproduce
1. Use the following command to bind 1 NIC port to DPDK driver:

dpdk-devbind.py -b vfio-pci 3d:00.0

2. Use the following command to build DPDK with clang compiler: 

rm -rf x86_64-native-linuxapp-clang 
CC=clang meson -Denable_kmods=True -Dlibdir=lib -Dbuildtype=debug
-Db_lundef=false -  Db_sanitize=address --default-library=static
x86_64-native-linuxapp-clang
ninja -C x86_64-native-linuxapp-clang

3. Execute the following command in the dpdk directory:

x86_64-native-linuxapp-clang/app/dpdk-testpmd -l 1-5 -n 4 -a 0000:3d:00.0 -- -i

[Show the output from the previous commands.]

    ethdev: add trace points

    Adds trace points for ethdev functions.

    The rte_ethdev_trace.h is removed. The file ethdev_trace.h is added as
    an internal header. ethdev_trace.h contains internal slow path and
    fast path tracepoints. The public fast path tracepoints are present in
    rte_ethdev_trace_fp.h header.
