Testing a few compiles here, this breaks when vector mode is disabled,
because it's possible that CC_AVX2_SUPPORT=1 when VECTOR=n. I'd suggest
adding "ifeq ($(CONFIG_RTE_LIBRTE_I40E_INC_VECTOR),y) ... endif" around the
block in the makefile checking for AVX2 support, so that we never set AVX2
unless we have vector support.
With this change, you can include my ack in v3.
