> 
> 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.
