So these are the patches needed to enable tunnel segmentation offloads on
the igb, igbvf, ixgbe, and ixgbevf drivers. In addition this patch extends
the i40e and i40evf drivers to include segmentation support for tunnels
with outer checksums.
The net performance gain for these patches are pretty significant. In the
case of i40e a tunnel with outer checksums showed the following
improvement:
Throughput Throughput Local Local Result
Units CPU Service Tag
Util Demand
%
14066.29 10^6bits/s 3.49 0.651 "before"
20618.16 10^6bits/s 3.09 0.393 "after"
For ixgbe similar results were seen:
Throughput Throughput Local Local Result
Units CPU Service Tag
Util Demand
%
12879.89 10^6bits/s 10.00 0.763 "before"
14286.77 10^6bits/s 5.74 0.395 "after"
These patches all rely on the TSO_MANGLEID and GSO_PARTIAL patches so I
would not recommend applying them until those patches have first been
applied.
