I create a rte_fib struct for rout=
ing purposes and I free it and recreate it
periodically to update the routes. rte_fib_create() uses
rte_cpu_get_flag_enabled() to check if my cpu has AVX512F or not and selects
lookup function according to it. My cpu does not have AVX512F so
rte_cpu_get_flag_enabled() returns 0 as expected and rte_fib_create() selec=
ts
scalar lookup function. However, after a point rte_cpu_get_flag_enabled()
causes a segmentation fault with SIGILL although it runs without any problem
until that moment.
