| | * | | | | | | iwlwifi: mvm: add rxf and txf to dump dataLiad Kaufman2015-01-22

This shouldn't happen in non-error statuses, as we don't want to stop the RXF/TXF while they are running.

When scanning on passive channels the firmware uses frag_passive_dwell to define the maximum continuous scan time before returning to the operating channel. On active channels max_out_time is the parameter used by the firmware to define the maximum time allowed out of the operating channel. Since active channels' scan should also be fragmented set max_out_time equal to frag_passive_dwell. In addition: - Set max_out_time and suspend_time if the firmware doesn't support fragmented scan to avoid unexpected behavior. - Adjust max_out_time for second level of scan precedence.

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.
