It consists of: - patch #2 hooks up the CT ops for the new mode in the right places. - patch #3 moves a function into a common file, so it can be reused. - patch #4 uses the HWS API to implement connection tracking. The main advantage of hardware steering compared to software steering is vastly improved performance when adding/removing/updating rules. Using the T-Rex traffic generator to initiate multi-million UDP flows per second, a kernel running with these patches was able to offload ~600K unique UDP flows per second, a number around ~7x larger than software steering was able to achieve on the same hardware (256-thread AMD EPYC, 512 GB RAM, ConnectX 7 b2b). ==================== Link: https://patch.msgid.link/20250114130646.1937192-1-tariqt@nvidia.com Signed-off-by: Jakub Kicinski --- 0b21051a4a6208c721615bb0285a035b416a4383
