Tuning rings size for performance optimization.

2015-01-15wil6210: relax spinlocks in rx reorderVladimir Kondratiev
In the Rx reorder mechanism, nothing is done in the interrupt context, so there is no need to use 'irq' flavors of spinlock. Rx done in NAPI context (tasklet), other manipulations - in the thread context. Having interrupts enabled makes it better for the OS in general. Besides, if enslaved under bonding, bridge or team driver, Rx won't work with interrupts disabled.

2015-01-15wil6210: add advanced interrupt moderationVladimir Kondratiev
Add advanced interrupt moderation support available since "Sparrow B0". Legacy interrupt moderation used only one counter to moderate tx, rx, and misc interrupts. Advanced interrupt moderation bypasses misc, and handles separately tx and rx interrupts. In addition it has two timers for each interrupt type. Max burst duration timer which defines how long to postpone interrupt after first event (receive event for rx and tx complete event for tx), and interframe timeout which defines how to determine the end of the burst and issue interrupt even if the first timer still pending. Capabilities flags in wil_priv is set on initialization according to HW. The rest of the code checks for advanced interrupt capability bit in capabilities flags field. Debugfs is split accordingly: "legacy" interrupt moderation remains unchanged, new debugs files added for advanced interrupt moderation support. Module params are aligned to support advanced interrupt moderation (tx & rx). When not available (for legacy interrupt moderation) will use only rx configuration; Tx configuration will be ignored in this case.

Eventually, it gets event confirming BACK agreement - WMI_BA_STATUS_EVENTID with negotiated parameters. On this event, update Tx vring data (struct vring_tx_data) and display BACK parameters on debugfs - recipient Rx side (recipient) firmware informs driver about ADDBA with WMI_RCP_ADDBA_REQ_EVENTID, driver process it in service work queue wq_service. It adjusts parameters and sends response with WMI_RCP_ADDBA_RESP_CMDID, and final confirmation provided by firmware with WMI_ADDBA_RESP_SENT_EVENTID. In case of success, driver updates Rx BACK reorder buffer. policy for BACK parameters: - aggregation size (agg_wsize * MPDUsize)) to not exceed 64Kbytes DELBA flow for: - originator driver decides to terminate BACK, it sends WMI_VRING_BA_DIS_CMDID and updates struct vring_tx_data associated with vring; ignore WMI_DELBA_EVENTID. - recipient firmware informs driver with WMI_DELBA_EVENTID, driver deletes correspondent reorder buffer ADDBA request processing requires sending WMI command, therefore it is processed in work queue context.
