Function Documentation
| static uint16_t rte_raw_cksum |
( |
const void * |
buf, |
|
|
size_t |
len |
|
) |
| |
|
inlinestatic |
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 224 of file rte_ip.h.
| static uint16_t rte_ipv4_cksum |
( |
const struct ipv4_hdr * |
ipv4_hdr | ) |
|
|
inlinestatic |
Process the IPv4 checksum of an IPv4 header.
The checksum field must be set to 0 by the caller.
- Parameters
-
| ipv4_hdr | The pointer to the contiguous IPv4 header. |
- Returns
- The complemented checksum to set in the IP packet.
Definition at line 243 of file rte_ip.h.
| static uint16_t rte_ipv4_phdr_cksum |
( |
const struct ipv4_hdr * |
ipv4_hdr, |
|
|
uint64_t |
ol_flags |
|
) |
| |
|
inlinestatic |
Process the pseudo-header checksum of an IPv4 header.
The checksum field must be set to 0 by the caller.
Depending on the ol_flags, the pseudo-header checksum expected by the drivers is not the same. For instance, when TSO is enabled, the IP payload length must not be included in the packet.
When ol_flags is 0, it computes the standard pseudo-header checksum.
- Parameters
-
| ipv4_hdr | The pointer to the contiguous IPv4 header. |
| ol_flags | The ol_flags of the associated mbuf. |
- Returns
- The non-complemented checksum to set in the L4 header.
Definition at line 269 of file rte_ip.h.
| static uint16_t rte_ipv4_udptcp_cksum |
( |
const struct ipv4_hdr * |
ipv4_hdr, |
|
|
const void * |
l4_hdr |
|
) |
| |
|
inlinestatic |
Process the IPv4 UDP or TCP checksum.
The IPv4 header should not contains options. The IP and layer 4 checksum must be set to 0 in the packet by the caller.
- Parameters
-
| ipv4_hdr | The pointer to the contiguous IPv4 header. |
| l4_hdr | The pointer to the beginning of the L4 header. |
- Returns
- The complemented checksum to set in the IP packet.
Definition at line 307 of file rte_ip.h.
| static uint16_t rte_ipv6_phdr_cksum |
( |
const struct ipv6_hdr * |
ipv6_hdr, |
|
|
uint64_t |
ol_flags |
|
) |
| |
|
inlinestatic |
Process the pseudo-header checksum of an IPv6 header.
Depending on the ol_flags, the pseudo-header checksum expected by the drivers is not the same. For instance, when TSO is enabled, the IPv6 payload length must not be included in the packet.
When ol_flags is 0, it computes the standard pseudo-header checksum.
- Parameters
-
| ipv6_hdr | The pointer to the contiguous IPv6 header. |
| ol_flags | The ol_flags of the associated mbuf. |
- Returns
- The non-complemented checksum to set in the L4 header.
Definition at line 355 of file rte_ip.h.
| static uint16_t rte_ipv6_udptcp_cksum |
( |
const struct ipv6_hdr * |
ipv6_hdr, |
|
|
const void * |
l4_hdr |
|
) |
| |
|
inlinestatic |
Process the IPv6 UDP or TCP checksum.
The IPv4 header should not contains options. The layer 4 checksum must be set to 0 in the packet by the caller.
- Parameters
-
| ipv6_hdr | The pointer to the contiguous IPv6 header. |
| l4_hdr | The pointer to the beginning of the L4 header. |
- Returns
- The complemented checksum to set in the IP packet.
