Definition in file rte_cksum.h. Function Documentation static uint16_t rte_raw_cksum (const void * buf, size_t len) [inline], [static] Process the non-complemented checksum of a buffer. Parameters buf Pointer to the buffer. len Length of the buffer. Returns The non-complemented checksum. Definition at line 94 of file rte_cksum.h. static int rte_raw_cksum_mbuf (const struct rte_mbuf * m, uint32_t off, uint32_t len, uint16_t * cksum) [inline], [static] Compute the raw (non complemented) checksum of a packet. Parameters m 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). Definition at line 117 of file rte_cksum.h. Author Generated automatically by Doxygen for DPDK from the source code.
