This series enables hardware GRO for ConnectX-7 and newer NICs. SHAMPO stands for Split Header And Merge Payload Offload. The first part of the series contains important fixes and improvements. The second part reworks the HW GRO counters. Lastly, HW GRO is perf optimized and enabled. Here are the bandwidth numbers for a simple iperf3 test over a single rq where the application and irq are pinned to the same CPU: +---------+--------+--------+-----------+-------------+ | streams | SW GRO | HW GRO | Unit | Improvement | +---------+--------+--------+-----------+-------------+ | 1 | 36 | 57 | Gbits/sec | 1.6 x | | 4 | 34 | 50 | Gbits/sec | 1.5 x | | 8 | 31 | 43 | Gbits/sec | 1.4 x | +---------+--------+--------+-----------+-------------+ Benchmark details: VM based setup CPU: Intel(R) Xeon(R) Platinum 8380 CPU, 24 cores NIC: ConnectX-7 100GbE iperf3 and irq running on same CPU over a single receive queue Series generated against: commit 83042ce9b7c3 ("Merge branch 'Felix-DSA-probing-cleanup'") Thanks, Tariq. V2: - Dropped the patch that adds no-split counters, we plan to add in the future with detailed documentation.
