[PATCH 0/2] Support for new Ethdev offload APIs

[Sunil Kumar Kori]

Patchset contains changes to support ethdev offload APIs for DPAA and DPAA2
drivers.

Offloading support is categoriesed in following logical parts:
1. If requested offloading features is not supported then returned error.
2. If requested offloading feature is supoorted but cannot be disabled then
   request to disable the offload is silently discarded with a message.
3. Otherwise configuration is succesfully offloaded

It is up to you but you may prefer to keep [rt]x_offload_capa in a variable or
macro so that you can use here directly without need to call dev_info, but that
is also OK if you prefer.

dev_info.rx_offload_capa is your device's offload capability. User may prefer to
utilize or not any of these offloads. So you can't return if requested offloads
are not equal to capability, this part is wrong.

Only you need to be sure that user is not asking more than what is supported.

[PATCH v2 0/2] Support for new Ethdev offload APIs

[Sunil Kumar Kori]

Patchset contains changes to support ethdev offload APIs for DPAA and DPAA2
drivers.

Offloading support is categoriesed in following logical parts:
1. If requested offloading features is not supported then returned error.
2. If requested offloading feature is supoorted but cannot be disabled then
   request to disable the offload is silently discarded with a message.
3. Otherwise configuration is succesfully offloaded

[Changes in v2]
1. Incorporated review comments.

Hi Hemant,

Overall this looks good to me, thanks.

Only I would like to ask if you prefer to replace nodis and not_supported checks.

Because with current order, if an offlaod requested that both has not supported
offload and not enable all nodis offloads, this will print both logs and return
error. Since it will return error, do you really need "non configurable" log?

If you replace checks, if any not supported offload requested it will only print
log for it and return error without checking/caring nodis offloads.

It is up to you, please let me know if you want to go with existing set.

Thanks,
ferruh
