2011-07-11iwlagn: consolidate the API that sends host commands and move to transportEmmanuel Grumbach
Now, there are only two functions to send a host command: * send_cmd that receives a iwl_host_cmd * send_cmd_pdu that builds the iwl_host_cmd itself and received flags The flags CMD_ASYNC / CMD_SYNC / CMD_WANT_SKB are not changed by the API functions.

2011-06-06iwlagn: use cts-to-self protection on 5000 adapters seriesStanislaw Gruszka
This patch fixes 802.11n stability and performance regression we have since 2.6.35. It boost performance on my 5GHz N-only network from about 5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz. These are test results of 5x downloading of approximately 700MB iso image: vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110 patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946 This was achieved with NetworkManager configured to do not perform periodical scans, by configuring constant BSSID. With periodical scans, after some time, performance downgrade to unpatched driver level, like in example below: patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683 However patch still make better here, since similar test on unpatched driver make link disconnects with below messages after some time: wlan1: authenticate with 00:23:69:35:d1:3f (try 1) wlan1: authenticate with 00:23:69:35:d1:3f (try 2) wlan1: authenticate with 00:23:69:35:d1:3f (try 3) wlan1: authentication with 00:23:69:35:d1:3f timed out On 2.6.35 kernel patch helps against connection hangs with messages: iwlagn 0000:20:00.0: queue 10 stuck 3 time.

2011-01-21iwlwifi: implement remain-on-channelJohannes Berg
For device supporting PAN/P2P, use the PAN context to implement the remain-on-channel operation using device offloads so that the filters in the device will be programmed correctly -- otherwise we cannot receive any probe request frames during off-channel periods.

2010-11-16iwlagn: fix PAN slot timing wrt. DTIMJohannes Berg

2010-10-06iwlagn: reduce redundant parameter definitionsWey-Yi Guy
move paramater definitions to a device paramater structure only leaving the device name, which antennas are used and what firmware file to use in the iwl_cfg structure. this will not completely remove the redundancies but greatly reduce them for devices that only vary by name or antennas. the parameters that are more likely to change within a given device family are left in iwl_cfg. also separate bt param structure added to help reduce more.

2010-09-11iwlwifi: fix and describe iwl_adjust_beacon_intervalJohannes Berg
The iwl_adjust_beacon_interval function is a bit of black magic, so add comments to it describing what it does. Also, in the case when there's no beacon interval set, program the default into the device (instead of adjusting, which results in the max) since using the max in that case interacts badly with dual-mode/PAN parameters. Also update the PAN parameters accordingly and use the same constant as here. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2010-09-11iwlwifi: avoid sending too many commandsJohannes Berg
When the PAN context is unused, there's no need to continually update it in the device. So track which contexts are active (with the special case that the WLAN context is always active ...) and only send their commands to the device when needed.

2010-09-11iwlwifi: fix PAN parameters while scanningJohannes Berg

2010-08-27iwlwifi: send PAN parametersJohannes Berg

2010-08-27iwlwifi: contextify command sendingJohannes Berg

2010-08-27iwlwifi: initial contextificationJohannes Berg
In order to support multiple interfaces, we must move a lot of data into per-context structures so we can use the contexts the device offers. To start with, this makes a lot of code context-aware, more changes will move more things into the context structure.

2010-08-09iwlagn: fix rts cts protectionJohannes Berg
Currently the driver will try to protect all frames, which leads to a lot of odd things like sending an RTS with a zeroed RA before multicast frames, which is clearly bogus. 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.

2010-07-23iwlwifi: add TLV to specify the size of phy calibration tableWey-Yi Guy

2010-06-25iwlwifi: name change from signal protection flagWey-Yi Guy
This bit need to be set for both RTS/CTS or CTS-to-self protection, if CTS-to-self is used, then uCode will check the RXON_FLG_SELF_CTS_EN status. Change the name from TX_CMD_FLG_RTS_CTS_MSK to TX_CMD_FLAG_PROT_REQUIRE_MSK to match the behavior of the bit setting. Also update comments to reflect which hardware uses which of the TX command flags. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>

2010-06-25iwlwifi: set TX_CMD_FLAG_PROT_REQUIRE_MSK in tx_flagWey-Yi Guy
When building tx command, always set TX_CMD_FLAG_PROT_REQUIRE_MSK for 5000 series and up. Without setting this bit the firmware will not examine the RTS/CTS setting and thus not send traffic with the appropriate protection. RTS/CTS is is required for HT traffic in a noisy environment where, without this setting, connections will stall on some hardware as documented in the patch that initially attempted to address this: commit 1152dcc28c66a74b5b3f1a3ede0aa6729bfd48e4 Author: Wey-Yi Guy <wey-yi.w.guy@intel.com> Date: Fri Jan 15 13:42:58 2010 -0800 iwlwifi: Fix throughput stall issue in HT mode for 5000 Similar to 6000 and 1000 series, RTS/CTS is the recommended protection mechanism for 5000 series in HT mode based on the HW design. Using RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment, it also prevent uCode encounter TX FIFO underrun and other HT mode related performance issues. For 3945 and 4965, different flags are used for RTS/CTS or CTS-to-Self protection. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
2010-06-05iwlwifi: do not clear data after chain noise calibShanyu Zhao

2010-04-16iwlwifi: trigger scan synchronouslyJohannes Berg
Scan requesting doesn't need to be asynchronous since all code paths leading up to it can sleep.
