Bug ID: 1286
Summary: cksum
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: testpmd
Assignee: dev@dpdk.org
Reporter: wa...@3snic.com
Target Milestone: ---
The code making sure sctp payload be multiple of 4 to determin TX_SCP_CKSUM in
process_inner_cksums() of csumonly.c should convert ipv4_hdr->total_length to
host byte order. The following is the code segment.
```
} else if (info->l4_proto == IPPROTO_SCTP) {
sctp_hdr = (struct rte_sctp_hdr *)
((char *)l3_hdr + info->l3_len);
/* sctp payload must be a multiple of 4 to be
* offloaded */
if ((tx_offloads & RTE_ETH_TX_OFFLOAD_SCTP_CKSUM) &&
((ipv4_hdr->total_length & 0x3) == 0)) {
ol_flags |= RTE_MBUF_F_TX_SCTP_CKSUM;
} else {
sctp_hdr->cksum = 0;
/* XXX implement CRC32c, example available in
* RFC3309 */
}
}
```
