Mellanox OFED 3.1 [1] comes with improved APIs that Mellanox ConnectX-4 (mlx5) adapters can take advantage of, such as:
- Separate post and doorbell operations on all queues. - Lightweight RX queues called Work Queues (WQs). - Low-level RSS indirection table and hash key configuration. This patchset enhances mlx5 with all of these for better performance and flexibility. Documentation is updated accordingly. [1] http://www.mellanox.com/page/products_dyn?product_family=26&mtag=linux_sw_drivers Changes in v2: - Fixed compilation errors due to a missing libibverbs callback in the first two commits. - Improved clean up in device stop function. - Added flows clean up when going promiscuous to save HW resources. - Removed VF check in promiscuous mode. - Added RSS support for IPv6 flows. - Renamed flow specification generator function. - Modified allmulticast code to use enhanced flow specifications. - Remaining changes are caused by rebase on v2 of the initial patchset ("Mellanox ConnectX-4 PMD (mlx5)").
