Not sure it is a fix.
The commit mentioned above allows some kind of offload config.
You are extending the offload config with support in
rte_eth_dev_set_vlan_offload().

DEV_RX_OFFLOAD_QINQ_STRIP was introduced in cc9d0456b870 ("i40e: support double vlan stripping and insertion"). But, the means to utilize this capability by enabling this rx offload for an ethdev was missing from the patch. The current patch fixes that missing functionality so that user can enable QinQ strip rx offload for capable devices.

It was possible to utilize the offload by setting the flag in mbuf.
You are adding a way to configure it at port level. So it is not a fix.

On its own patch looks ok but a few high level questions:

1- Why we need this interim defines, instead of using actual offload values?
Although changing this will be API/ABI breakage.

2- Why we have specific function to set vlan offloads, for other offloads the
way is stop device and reconfigure it with new offload flags.

3- If devices can change offload configuration dynamically, do we need a generic
API to alter the offload configs? (similar to these vlan APIs but more generic)?



Related to the patch, what do you think about following options:
a)
- Get this patch
- Send a deprecation notice for 1) in this release
- Next release remove these flags, which will be practically reverse this patch
and more

b)
- Send a deprecation notice for 1) in this release
- Next release update the APIs and a smaller/different version of this patch
will be required.

If dynamic switching of offloads is really required, I think it would be
good if it is unified. If so, we can deprecate
rte_eth_dev_{s,g}et_vlan_offload() and implement it using the new one
to remove the old one from driver interface at least.
It requires reporting of dynamically switchable offloads on device and
queue level. Or just dynamically switchable offloads in assumption that
if the offload is supported on queue level and dynamically switchable,
it is dynamically switchable on queue level.

I'm OK with both options, but I think it would be fair to go (a) to avoid
postponing of the feature too long.

The patch itself should update rte_eth_dev_{s,g}et_vlan_offload()
descriptions which enumerate switchable offloads.

Not sure if "dynamic switching of offloads" required, but I agree we may need to
add "dynamically switchable offload" reporting for that.

@Vivek, can you please send a new version with this update?

[dpdk-dev] [PATCH v4] ethdev: support QinQ strip dynamic configuration

[viveksharma]

From: Vivek Sharma <viveksharma@marvell.com>

Enable missing support for runtime configuration (setting/getting)
of QinQ strip rx offload for a given ethdev.

Signed-off-by: Vivek Sharma <viveksharma@marvell.com>
---
v4:
* Update vlan offload set/get functions description.

v3:
* Make patch as 'non-fix'.

v2:
* Use pointer to dereference dev->data->dev_conf.rxmode.offloads.

Hi Andrew,

As far as I understand you were OK with the patch after change, can I add your ack?

Yes, please. I've tried to find some time to double-check consistency
vs supported offloads and error reporting, but have not found time yet
to do it. Let's apply and I'll keep it in mind to take a look later.

Thanks,
Andrew.
