staticuint16_trte_raw_cksum(constvoid*buf,size_tlen)[inline],[static]
       Process the non-complemented checksum of a buffer.

       Parametersbuf Pointer to the buffer.
           len Length of the buffer.

       Returns
           The non-complemented checksum.

       Definition at line 94 of file rte_cksum.h.

   staticintrte_raw_cksum_mbuf(conststructrte_mbuf*m,uint32_toff,uint32_tlen,uint16_t*cksum)[inline],[static]
       Compute the raw (non complemented) checksum of a packet.

       Parametersm The pointer to the mbuf.
           off The offset in bytes to start the checksum.
           len The length in bytes of the data to checksum.
           cksum A pointer to the checksum, filled on success.

       Returns
           0 on success, -1 on error (bad length or offset).
