From: Alex Vesker > ConnectX and BlueField devices which support HWS are capable of > performing advanced match, range-match and hashing operations on packet > headers. This patch-set introduces support for (1) range matching - allows > combining range and exact match over provided item fields using spec, last > and mask. > A useful example for Range and exact match is matching exact IP and port > range. This series also introduces (2) partial hash, which allows using the > same matcher and performing partial hashing in case of multiple match > templates are provided. The matcher create code finds the union and > intersection fields to split the hash and match in a way the HW can support. > This increases the match templates combinations possible although it may > limit the maximum PPS. Since (1) and (2) are not fully support on current HW > the implementation is done on top of a HW like FW API using WQEs. > > v2: > -Fix missed checkpatch comments > > Alex Vesker (16): > net/mlx5/hws: support synchronous drain > net/mlx5/hws: matcher remove AT and MT limitation > net/mlx5/hws: support GTA WQE write using FW command > net/mlx5/hws: add capability query for gen wqe command > net/mlx5/hws: align RTC create command with PRM format > net/mlx5/hws: add send FW match STE using gen WQE > net/mlx5/hws: add send FW range STE WQE > net/mlx5/hws: move matcher size check to function > net/mlx5/hws: support range match > net/mlx5/hws: redesign definer create > net/mlx5/hws: support partial hash > net/mlx5/hws: add range definer creation support > net/mlx5/hws: add FW WQE rule creation logic > net/mlx5/hws: add debug dump support for range and hash > net/mlx5/hws: rename pattern cache object > net/mlx5/hws: cache definer for reuse
