Hello,

I am having this problem when launching any DPDK application (including
helloworld):
illegal instruction (core dumped). I have tried to install several version
of DPDK: V22.11 V22.03 and 23.03 and non of them are working. I have
configure meson to build as a generic and native platform and non of them
are working.

DPDK requires at least SSE 4.2 (Nehalem),
your CPU only has SSE 4.1 (Wolfdale).
