Hi Konstantin,
We have add this case to test avx512 mode, if this judgment is not added, the cmdline will invalid.

Take a example:
x86_64-native-linuxapp-gcc/app/test/dpdk-test -l 1,2,3,4 -n 4 --file-prefix=dpdk_237965_20211103034106 --force-max-simd-bitwidth=512 --no-pci --force-max-simd-bitwidth=0
