Flow rules performance with ConnectX-6 Dx

[Dmitry Kozlyuk]

Hi Dmitry,

Can it be that RSS, to which non-matching traffic gets by default,
is configured in a way that steers each destination IP to one queue?
And this 15 Mpps is in fact how much a core can read from a queue?
In general, it is always worth trying to reproduce the issue with testpmd
and to describe flow rules in full testpmd format ("flow create...").
