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.
