Bug ID: 1485
Summary: Checksum function should require the whole packet to
be on one segment
Product: DPDK
Version: 24.07
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: doc
Assignee: dev@dpdk.org
Reporter: user202...@protonmail.com
Target Milestone: ---
The function rte_ipv4_udptcp_cksum (and probably also
rte_ipv4_udptcp_cksum_verify ) does not work properly when the header is taken
from a mbuf that consist of multiple segments.
I suggest editing the documentation to say e.g. "if the header is taken from a
mbuf with e.g. rte_pktmbuf_mtod which potentially consist of multiple segments,
use rte_ipv4_udptcp_cksum_mbuf instead."
