2009-10-07iwlwifi: LED cleanupJohannes Berg
The iwlwifi drivers have LED blinking requirements that mac80211 cannot fulfill due to the use of just a single LED instead of different ones for TX, RX, radio etc. Instead, the single LED blinks according to transfers and is solid on the rest of the time. As such, having LED class devices registered that mac80211 triggers are connected to is pointless as we don't use the triggers anyway. Remove all the useless code and add hooks into the driver itself. At the same time, make the LED code abstracted so the core code that determines blink rate etc. can be shared between 3945 and agn in iwlcore. At the same time, the fact that we removed the use of the mac80211 LED triggers means we can also remove the IWLWIFI_LEDS Kconfig symbol since the LED support is now self-contained.

2009-10-07iwlwifi: device tracingJohannes Berg
In order to have an easier way to debug issues, create trace events (using the ftrace framework) that will allow us to follow exactly what the driver is doing with the device. The text format isn't all that useful, but the binary format can also be obtained easily via debugfs and then analysed on the fly or offline with debugging tools.

2009-10-07iwlwifi: set default aggregation frame count limit to 31Wey-Yi Guy
Multiple MPDUs can be aggregated, transmitted, and finally acknowledged together using a single BA frame. Block ACK (BA) contains bitmap size of 64*16 bits so the maximum frame count is 64. The default value of aggregation frame count suggested by uCode is 31 to achieve best performance.

2009-10-07iwlwifi: reliable entering of critical temperature stateWey-Yi Guy
When uCode detects critical temperature it should send "card state notification" interrupt to driver and then shut itself down to prevent overheating. There is a race condition where uCode shuts down before it can deliver the interrupt to driver. Additional method provided here for driver to enter CT_KILL state based on temperature reading. How it works: Method 1: If driver receive "card state notification" interrupt from uCode; it enters "CT_KILL" state immediately Method 2: If the last temperature report by Card reach Critical temperature, driver will send "statistic notification" request to uCode to verify the temperature reading, if driver can not get reply from uCode within 300ms, driver will enter CT_KILL state automatically. Method 3: If the last temperature report by Card did not reach Critical temperature, but uCode already shut down due to critical temperature. All the host commands send to uCode will not get process by uCode; when command queue reach the limit, driver will check the last reported temperature reading, if it is within pre-defined margin, enter "CT_KILL" state immediately. In this case, when uCode ready to exit from "CT_KILL" state, driver need to restart the adapter in order to reset all the queues and resume normal operation. One additional issue being address here, when system is in CT_KILL state, both tx and rx already stopped, but driver still can send host command to uCode, it will flood the command queue since card was not responding; adding STATUS_CT_KILL flag to reject enqueue host commands to uCode if it is in CT_KILL state, when uCode is ready to come out of CT_KILL, driver will clear the STATUS_CT_KILL bit and allow enqueue the host commands to uCode to recover from CT_KILL state.

2009-10-07iwlwifi: add aggregation tables to the rate scaling algorithmDaniel C Halperin
Current rate scale algorithm fluctuates between different MIMO modes fairly rapidly, causing widely varying performance. These fluctuations occur because in the rate_scale tables for expected throughput the values are not very different for different modes. However, when aggregation is turned on and MAC overhead is reduced, the expected throughput for different MIMO modes grows and different modes have vastly different performance. Add expected throughput tables for this case. We also need to keep track of aggregation status per-station, so we add the "is_agg" field to struct lq_sta. Also includes cleanup of comments and variable names in/around the affected code.

2009-10-07iwlwifi: Use RTS/CTS as the preferred protection mechanism for 6000 seriesWey-Yi Guy
When 802.11g was introduced, we had RTS/CTS and CTS-to-Self protection mechanisms. In an HT Beacon, HT stations use the "Operating Mode" field in the HT Information Element to determine whether or not to use protection. The Operating Mode field has 4 possible settings: 0-3: Mode 0: If all stations in the BSS are 20/40 MHz HT capable, or if the BSS is 20/40 MHz capable, or if all stations in the BSS are 20 MHz HT stations in a 20 MHz BSS Mode 1: used if there are non-HT stations or APs using the primary or secondary channels Mode 2: if only HT stations are associated in the BSS and at least one 20 MHz HT station is associated. Mode 3: used if one or more non-HT stations are associated in the BSS. When in operating modes 1 or 3, and the Use_Protection field is 1 in the Beacon's ERP IE, all HT transmissions must be protected using RTS/CTS or CTS-to-Self. By default, CTS-to-self is the preferred protection mechanism for less overhead and higher throughput; but using the full RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment. For 6000 series WIFI NIC, RTS/CTS protection mechanism is the recommended choice for HT traffic based on the HW design.

2009-10-07iwlwifi: clarify and clean up chain settingsJohannes Berg
The chain settings we currently use in iwlwifi are rather confusing -- and we also go by the wrong settings entirely under certain circumstances. To clean it up, create a new variable in the current HT config -- single_chain_sufficient -- that tells us whether we need more than one chain. Calculate that based on the AP and operating mode (no IBSS HT implemented -- so no need for multiple chains, for station mode we use the AP's capabilities). Additionally, since APs always send disabled SM PS mode, keeping track of their sm_ps mode isn't very useful -- doubly not so for our _own_ RX config since that should depend on our, not the AP's, SM PS mode. Finally, document that our configuration of the number of RX chains used is currently wrong when in powersave (by adding a comment). All together this removes the two remaining items in struct iwl_ht_config that were done wrong there. For the future, the number of RX chains and some SM PS handshaking needs to be added to mac80211, which then needs to tell us, and the new variable current_ht_config.single_chain_sufficient should also be calculated by mac80211.
