- For x86, it allows other apps such as OVS and VPP which already make use of
  AVX-512 to indicate that they are happy for DPDK to use AVX-512 too.
- It allows the end-user to override those settings if so desired.
- For all architectures, it allows an easy way to disable vector code or limit 
vector
  length if so desired, which can be useful for testing.
