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	dev@dpdk.org

Currently, the documentation of RT=
E_MBUF_F_TX_UDP_CKSUM in
https://doc.dpdk.org/api/rte__mbuf__core_8h.html#ada511=
d6f30184b374ba2248c26af8ede
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.c=
om/amzn/amzn-drivers/issues/79 states that you need to set
m3_len, total_length, dgram_cksum to the pseudo-header checksum etc. (not s=
ure
about this).

What is the actual requirement of that flag, and how should the documentati=
on
be edited?
