[PATCH 1/2] common/sfc_efx/base: add API to drop MAE action resource IDs

[PATCH 1/2] common/sfc_efx/base: add API to drop MAE action resource IDs

[Ivan Malov]

When the client driver (the DPDK one, for instance) parses user flow
actions, it ends up with an action set specification. Next, in case
there are any FW resource-backed actions, like COUNT or SET_DST_MAC,
the driver allocates these resources and indicates their IDs in the
action set specification. The API used to set these IDs checks that
the current value of the target ID is INVALID, prior to the call.

The latter check, however, prevents the driver from updating the
IDs on port restart. When the port goes down, the driver frees
the resources. When the port goes up, the driver reallocates
them, tries to set the IDs in the specification and fails.

In order to address the problem, add an API to drop the
current resource IDs in the actions set specification.

[PATCH 2/2] net/sfc: invalidate dangling MAE flow action FW resource IDs

[Ivan Malov]

When reinserting a flow (on port restart, for instance)
FW resource IDs found in the action set specification
need to be invalidated so that the new (reallocated)
FW resource IDs can be accepted by libefx again.

Hi Ivan,

As far as I understand this patch extracts some code into a function, so
I expect no functional change in this patch. So not clear what this
patch is fixing?

And I can see this new API is used in next patch and it fixes an issue.
But while backporting this fix to LTS we want both patch to backport
because there is a dependency.

If there is no functional change in this patch, what about merging these
two patches, and explain what is fixed? This also helps backporting.

As far as I know, changes to different trees (common/sfc_efx/base on the
one hand and drivers/net/sfc on the other) belong in separate patches.
Please correct me in case I've got that wrong.

Anyway, if it's not that hard to backport the two patches in their
current state, I vote for keeping them like that. I don't insist.

Thank you.

I think changes are simple and can go into single patch to help
dependency between two.

Thanks for perseverance. Now you mention it, what prefix in the summary
should I use? Just "drivers: "? For the unified patch, that is.
