Hi Bruce,
Just curious, can you provide some hints on percent increase in at least
some representative cases? I'm just trying to get a sense of if this is
%5, 10%, 20%, more... I know mileage will vary depending on system, setup,

This patch adds an AVX2 vectorized path to the i40e driver, based on the
existing SSE4.2 version. Using AVX2 instructions gives better performance
than the SSE version, though the percentage increase depends on the exact
settings used. For example:
* Using 16B rather than 32B descriptors gives the
8 matches
