Please disregard the original test result as it is inaccurate. I have
tested the patch on the N1SDP platform with an Intel Corporation Ethernet
Controller XL710 for 40GbE QSFP+ using a single core and testpmd rxonly
mode. With this test, there is no significant performance difference between
the scalar Rx path and the vector PMD Rx path for iavf on Arm. The same
result was observed with i40e when comparing its scalar and its vector PMD
Rx paths on Arm. I will update the commit message accordingly.
