2011-05-02rt2x00: Reduce tx status reading timeoutIvo van Doorn
When no TX status was available, the default timeout of 20ms is a bit high. The frame is highly likely already send out, so the TX status should be available within only a few milliseconds.

2011-05-02Revert "wl12xx: support FW TX inactivity triggers"Luciano Coelho
This reverts commit 47684808fd89d6809c0886e06f8ac324252499d8. Conflicts: drivers/net/wireless/wl12xx/conf.h drivers/net/wireless/wl12xx/main.c
2011-05-02wl12xx: export driver state to debugfsArik Nemtsov
By reading the "driver_state" debugfs value we get all the important state information from the wl12xx driver. This helps testing and debugging, particularly in situations where the driver seems "stuck". Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-05-02wl12xx: fix race condition during recovery in AP modeArik Nemtsov
When operating as AP, the TX queues are not stopped when we start recovery. mac80211 is notified only after the fact. When there is pending TX, it will be queued even after the FW is down. This leads to situations where the TX queues are stopped (because of the TX-watermark mechanism), and are never woken up when we return from recovery. Fix this by explicitly stopping the TX queues when before initiating recovery. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-05-02wl12xx: AP-mode - overhaul rate policy configurationArik Nemtsov
Use the minimal rate configured in the basic rates set as the AP broadcast and multicast rate. The minimal rate is used to ensure weak links can still communicate. When the basic rates contains at least one OFDM rate, configure all unicast TX rates to OFDM only. Unify rate configuration on initialization and on change notification into a single function.

2011-05-02wl12xx: print firmware program counter during recoveryArik Nemtsov
When performing recovery, print the firmware version and program counter (by reading the SCR_PAD4 register). The value of the firmware program counter during assert can be useful for debugging. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-05-02wl12xx: schedule recovery on command timeoutArik Nemtsov
We use a long timeout (2 seconds) when sending commands to the FW. When a command times out, it means the FW is stuck, and we should commence recovery. This should make recovery times shorter as we'll recover on the first timeout indication. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-05-02wl12xx: use wiphy values for setting rts, frag thresholds on initArik Nemtsov
Use the wiphy RTS and fragmentation thresholds for initializing the FW when possible. This mitigates a bug where previously set values are forgotten after interface down/up. Add checks before settings these values to ensure they are valid. Use default values when invalid thresholds are configured.

2011-05-02wl12xx: implement the tx_frames_pending mac80211 callbackArik Nemtsov
Frames are considered pending when they reside in the driver TX queue or already queued in the FW. This notion of "pending" is appropriate for power save considerations in STA mode, but not necessarily in other modes (for instance P2P-GO).

2011-05-02wl12xx: Enable dynamic memory for 127xIdo Yariv
The FW can dynamically manage its internal TX & RX memory pools, moving blocks from one pool to another when necessary. This can significantly improve performance. Currently this feature is enabled only for 128x. Enable dynamic memory for 127x as well. Other parameters in the memory configuration structure may need to be fine tuned, as the optimal values for these may change once dynamic memory is enabled.

2011-05-02wl12xx: Restart TX when TX descriptors are availableIdo Yariv
The driver stops sending TX packets when either there aren't enough memory blocks, or it runs out of TX descriptors. The driver continues to send packets to the FW only when more memory blocks are available. The FW might free TX descriptors without freeing the corresponding memory blocks, especially when dynamic memory is enabled. In cases where memory blocks are not freed at all, the driver will keep waiting for more memory blocks indefinitely. Fix this by clearing the WL1271_FLAG_FW_TX_BUSY flag when there are available TX descriptors. Signed-off-by: Ido Yariv <ido@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-05-02wl12xx: Modify memory configuration for 128x/APIdo Yariv
The 128x/AP firmware does not yet support dynamic memory. Temporarily, the memory configuration for the 127x was used both for 127x/AP as well as 128x/AP. Since the two chips don't have the same number of memory blocks, TP was significantly degraded. This hasn't been fine tuned yet, but using the base 128x numbers (without dynamic memory) seems to yield much better results (around 30% more). Additional fine tuning will be required in the future.

2011-05-02wl12xx: configure rates when working in ibss modeEliad Peller
When working in ibss mode, we don't configure rate policy per station (as we use the same link for multiple stations), so currently the 1mb/s rate is being used.

2011-05-02wl12xx: avoid redundant join on interface reconfigurationEliad Peller
ieee80211_reconfig() sets most of the "changed" flags regardless of the actual change (e.g. BSS_CHANGED_ASSOC will be set even if the interface is still not associated). in this case the driver will issue some unneeded commands. Since the driver relies solely on the BSS_CHANGED_ASSOC flag, without checking if there was an actual change, it will end up issuing unjoin() and dummy_join() commands, although it was never associated and should just remain idle. Avoid it by checking the actual state change, in addition to the "changed" flag. (there seem to be more redundant configuration commands being issued, but they shouldn't harm) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-05-02wl12xx: print actual rx packet size (without padding)Eliad Peller

2011-05-02wl12xx: avoid premature elp entranceEliad Peller
The elp_work is being enqueued on wl1271_ps_elp_sleep, but doesn't get cancelled on wl1271_ps_elp_wakeup. This might cause immediate entrance to elp when the wl->mutex is being released, rather than using the delayed enqueueing optimization. Cancel elp_work on wakeup request, and add a new WL1271_FLAG_ELP_REQUESTED flag to further synchronize the elp actions.

2011-04-30iwlagn: prefer BSS contextJohannes Berg
If an interface type changes from a type that is only supported on the PAN context (e.g. P2P GO) to a type that is supported on the BSS context, and the BSS context is not in use, then we need to use the BSS context instead of changing the device type within the context. To achieve this, refuse the type change, which causes a down/up cycle that will allocate the BSS context for the interface.

The current RXON checking doesn't verify that the channel is valid (or at least non-zero), so add that.

2011-04-30iwlagn: introduce silent grabbing of NIC accessJohannes Berg
There are a few cases like the WoWLAN support I'm writing that require attempting to access the NIC when it is known that it might not be accessible, e.g. after the system woke up and the platform might have reset the device.

2011-04-30iwlagn: avoid hangs when restarting deviceJohannes Berg
If a device error happens while the uCode is being loaded or initialised, we will attempt to restart the device (which will likely fail again, but that's not the issue here). During this new restart, we turn off the device, but as the uCode failed to initialise it already is turned off. As a consequence, grabbing NIC access will fail and cause excessive messages and hangs. To fix this issue, introduce a new status bit and only attempt to reprogram the device when it isn't already disabled.

2011-04-29ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny
This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation.

2011-04-29ethtool: Call ethtool's get/set_settings callbacks with cleaned dataDavid Decotigny
This makes sure that when a driver calls the ethtool's get/set_settings() callback of another driver, the data passed to it is clean. This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline.
