      cxgb4: remove cast when saving IPv4 partial checksum · 2f667016
      Rahul Lakkireddy authored
      The checksum field in IPv4 header is in __sum16 and ip_fast_csum()
      also returns __sum16. So, no need to cast it to u16.

      cxgb4: fix endian conversions for L4 ports in filters · 63b53b0b
      Rahul Lakkireddy authored
      The source and destination L4 ports in filter offload need to be
      in CPU endian. They will finally be converted to Big Endian after
      all operations are done and before giving them to hardware. The
      L4 ports for NAT are expected to be passed as a byte stream TCB.
      So, treat them as such.
