  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: 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
