* [dpdk-stable] [PATCH] ethdev: update qfi definition

qfi field is 8 bits which represent single bit for
PPP (paging Policy Presence) single bit for RQI
(Reflective QoS Indicator) and 6 bits for qfi
(QoS Flow Identifier)

This update the doxygen format and the mask for qfi
to properly identify the full 8 bits of the field.

note: changing the default mask would cause different
patterns generated by testpmd.

Fixes: 346553db5bd1 ("ethdev: add GTP extension header to flow API")

By design requirement, rte_flow_item_* should start with the relevant protocol 
header.

There is already a deprecation notice for using protocol header directly in the 
rte_flow_item* [1] and Adrew/Ivan already fixed a few of them [2].

Your patch is not directly related on this, but since you are touching to the 
flow_item, would you mind create a protocol struct for it first, and use it in 
the "struct rte_flow_item_gtp_psc"?
So the protocol related update can be done in the protocol header, instead of 
rte_flow struct.

Sure, I can create the new protocol and use it , and will send in V2. But, wouldn't it cause any ABI breakage ?

For the protocol header, it won't be problem since it is a new struct.

For the flow item struct, it may be, that is why need to use a union for now, 
please check what Adrew/Ivan did.

* [dpdk-stable] [PATCH v2 2/2] ethdev: update qfi definition
       [not found] ` <20210330075036.6579-1-rasland@nvidia.com>
@ 2021-03-30  7:50   ` Raslan Darawsheh
  0 siblings, 0 replies; 7+ messages in thread
From: Raslan Darawsheh @ 2021-03-30  7:50 UTC (permalink / raw)
  To: dev; +Cc: viacheslavo, shirik, ying.a.wang, stable

qfi field is 8 bits which represent single bit for
PPP (paging Policy Presence) single bit for RQI
(Reflective QoS Indicator) and 6 bits for qfi
(QoS Flow Identifier) based on RFC 38415-g30

This update the doxygen format and the mask for qfi
to properly identify the full 8 bits of the field.

note: changing the default mask would cause different
patterns generated by testpmd.

Fixes: 346553db5bd1 ("ethdev: add GTP extension header to flow API")

Cc: stable@dpdk.org

Applied to dpdk-next-net/main, thanks.


Sorry for going through multiple versions, hopefully proper solution can be 
merged after deprecation notice on v21.11.
