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).
