Bug ID	1485
Summary	Checksum function should require the whole packet to be on on= e segment
Product	DPDK
Version	24.07

Status	UNCONFIRMED
Severity	normal

The function rte_ipv4_udptcp_cksum=
 (and probably also
rte_ipv4_udptcp_cksum_verify ) does not work properly when the header is ta=
ken
from a mbuf that consist of multiple segments.

I suggest editing the documentation to say e.g. "if the header is take=
n from a
mbuf with e.g. rte_pktmbuf_mtod which potentially consist of multiple segme=
nts,
use rte_ipv4_udptcp_cksum_mbuf instead."
