Hey, these patches enable support for software IRQ coalescing and GRO aggregation and applies conservative defaults which can help improve system and network performance by reducing the number of hardware interrupts and improving GRO aggregation ratio.
Without this patch, seeing the following with an iperf3 server running
at a gigabit link:
00:18:19 CPU %usr %nice %sys %iowait %irq %soft %steal
%guest %idle
00:18:20 all 0.53 0.00 9.36 0.00 8.56 18.98 0.00
0.00 62.57
and with your patches applied:
00:00:56 CPU %usr %nice %sys %iowait %irq %soft %steal
%guest %idle
00:00:57 all 0.00 0.00 3.29 0.00 1.01 7.34 0.00
0.00 88.35
so definitively helping, thanks!

You will have to repost once net-next opens though:
