Bug ID: 1488
Summary: Suggestion: add documentation to fill in total_length
etc. to UDP checksum offloading?
Product: DPDK
Version: 24.07
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: doc
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Currently, the documentation of RTE_MBUF_F_TX_UDP_CKSUM in
https://doc.dpdk.org/api/rte__mbuf__core_8h.html#ada511d6f30184b374ba2248c26af8ede
is very sparse:
> UDP cksum of TX pkt. computed by NIC.
I think it should mention which fields should be set.
Some bug reports e.g. https://github.com/amzn/amzn-drivers/issues/176
https://github.com/amzn/amzn-drivers/issues/79 states that you need to set
m3_len, total_length, dgram_cksum to the pseudo-header checksum etc. (not sure
about this).
What is the actual requirement of that flag, and how should the documentation
be edited?
