This maintenance is far from ideal - there's no real reason why QED needs to maintain such a data-structure.

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.
