Subject: Re: Could not achieve wire speed for 40GE with any DPDK version on XL710 NIC's

DISCLAIMER: This information is not verified. This is truly my personal
opinion.
As I know, intel 82599 is the only 10G NIC which supports line rate with
minimum sized packets (64 byte).
According to our internal tests, Mellanox's 40G NICs even support less than
30Mpps.
I think 40 Mpps is the hardware capacity.
