This patch introduces a meson option to disable the AVX2 support.
If the build should be for a target without AVX2 support, the
know can be turned to false, even if the compiler supports AVX2.

Hi,
This code does not appear in the upstream DPDK project [1]. This looks like
a pktgen patch instead, is this the case? If so, please put pktgen
