* iwlwifi: jiffies based tx queues watchdogStanislaw Gruszka2010-12-061-15/+6Star
| | | | | | | | | | | | | | | This patch replace monitor/recover timer by watchdog based on time stamp. New code allow to discover hangs more precisely. Timeout values are currently doubled monitoring period values of previous timer. This have to be tuned based of firmware timing capabilities. Tested on 3945, 4965, 5300, 6300.

* | iwlagn: new RXON processing for modern devicesJohannes Berg2010-11-151-14/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to simplify the flow, and make new enhancements easier, separate out the RXON processing for modern AGN (5000 and newer) from RXON processing for the older 3945 and 4965 devices. Avoid changing these old ones to avoid regressions and move their code to a new file (iwl-legacy.c). 4965 gets the commit_rxon that used to be common for all AGN devices, but with removed PAN support. The new RXON processing is more central and does more work in committing, so that it is easier to follow. To make it more evident what is split out for legacy, split the necessary operations for that into a new struct iwl_legacy_ops. Those parts that still exist in the new AGN code don't need to be parametrized.

* | iwlwifi: avoid commit rxon during scan in iwlagn_configure_filterStanislaw Gruszka2010-11-151-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Almost anywhere in the code we avoid committing rxon while performing scan, and make rxon commit when scan complete. However in some places in the code we do not follow that rule. This patch fix that problem in iwlagn_configure_filter(). Since we do not commit directly in iwl3945_configure_filter, we can also do the same for agn, so I just remove iwlcore_commit_rxon() function and add a comment. Also change comment for iwl3945.

In order to fix all of this, we need to take a step back and see what we need to achieve: * we need RTS/CTS protection if requested by the AP for the BSS, mac80211 tells us this * in that case, CTS-to-self should only be enabled when mac80211 tells us * additionally, as a hardware workaround, on some devices we have to protect aggregated frames with RTS To achieve the first two items, set up the RXON accordingly and set the protection required flag in the transmit command when mac80211 requests protection for the frame. To achieve the last item, set the rate-control RTS-requested flag for all stations that we have aggregation sessions with, and set the protection required flag when sending aggregated frames (on those devices where this is required). Since otherwise bugs can occur, do not allow the user to override the RTS-for-aggregation setting from sysfs any more. Finally, also clean up the way all these flags get set in the driver and move everything into the device-specific functions.
