Hello,

DPDK 22.03 contains quite some changed to the ICE driver and the
implementation for the Intel E810-C card, I'm running some tests and while switching to this new version from 21.02 I see a degradation of
performance of around 30% using 4 capture core with 40Gbps rate (64bytes frame), packets are random and evenly distributed among the cores.

Leaving unchanged all the other factors and only updating the library I
start observing substantial packet drops, using igb_uio and firmware
version 3.00 0x80008256 1.2992.0, I do not see any drop with 21.02.

Is there any novel configuration to be made during initialization of the card or something like that? Anyone else is observing performance drop
with the new dpdk?

Thanks
