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!
