qed*: Handle-based L2-queues.
The driver needs to maintain several FW/HW-indices for each one of
its queues. Currently, that mapping is done by the QED where it uses
an rx/tx array of so-called hw-cids, populating them whenever a new
queue is opened and clearing them upon destruction of said queues.
This maintenance is far from ideal - there's no real reason why
QED needs to maintain such a data-structure. It becomes even worse
when considering the fact that the PF's queues and its child VFs' queues
are all mapped into the same data-structure.
As a by-product, the set of parameters an interface needs to supply for
queue APIs is non-trivial, and some of the variables in the API
structures have different meaning depending on their exact place
in the configuration flow.
This patch re-organizes the way L2 queues are configured and maintained.
In short:
- Required parameters for queue init are now well-defined.
- Qed would allocate a queue-cid based on parameters.
Upon initialization success, it would return a handle to caller.
- Queue-handle would be maintained by entity requesting queue-init,
not necessarily qed.
- All further queue-APIs [update, destroy] would use the opaque
handle as reference for the queue instead of various indices.
The possible owners of such handles:
- PF queues [qede] - complete handles based on provided configuration.
- VF queues [qede] - fw-context-less handles, containing only relative
information; Only the PF-side would need the absolute indices
for configuration, so they're omitted here.
- VF queues [qed, PF-side] - complete handles based on VF initialization.

qed*: Handle-based L2-queues.
The driver needs to maintain several FW/HW-indices for each one of
its queues. Currently, that mapping is done by the QED where it uses
an rx/tx array of so-called hw-cids, populating them whenever a new
queue is opened and clearing them upon destruction of said queues.
This maintenance is far from ideal - there's no real reason why
QED needs to maintain such a data-structure. It becomes even worse
when considering the fact that the PF's queues and its child VFs' queues
are all mapped into the same data-structure.
As a by-product, the set of parameters an interface needs to supply for
queue APIs is non-trivial, and some of the variables in the API
structures have different meaning depending on their exact place
in the configuration flow.
This patch re-organizes the way L2 queues are configured and maintained.
In short:
- Required parameters for queue init are now well-defined.
- Qed would allocate a queue-cid based on parameters.
Upon initialization success, it would return a handle to caller.
- Queue-handle would be maintained by entity requesting queue-init,
not necessarily qed.
- All further queue-APIs [update, destroy] would use the opaque
handle as reference for the queue instead of various indices.
The possible owners of such handles:
- PF queues [qede] - complete handles based on provided configuration.
- VF queues [qede] - fw-context-less handles, containing only relative
information; Only the PF-side would need the absolute indices
for configuration, so they're omitted here.
- VF queues [qed, PF-side] - complete handles based on VF initialization.
