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. Signed-off-by:

The current RXON checking doesn't verify that the channel is valid (or at least non-zero), so add that. Also, add a WARN() so we get a stacktrace, and capture a bitmask of errors in order to capture all necessary information in the warning itself (in case the previous messages are snipped off.)

This header file isn't used, and if we ever need these definitions they shouldn't be added to a driver but rather to the common 802.11 include file that has all frame definitions. Thus, just remove it. Signed-off-by:

New microcode versions use the good CRC threshold field differently, as a flag, and in that case we should set it to 1/0 instead of 1/65535 for an active/passive scan. The new behaviour is advertised by the uCode with a feature flag. Signed-off-by:

The WoWLAN resume code will have to essentially do a restart, but without going through the work struct. To support that, refactor the restart by splitting out the preparation code into a new function. Signed-off-by:

Johannes Berg authored
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. To avoid messages in this case, introduce the new function iwl_grab_nic_access_silent(), it will only return an error status. Signed-off-by:

Johannes Berg authored
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. Signed-off-by:

The tx_headroom required for mwl8k driver is 32 bytes and it can use the space for 802.11 header received from mac80211. mwl8k considers the smallest 802.11 frame (CTS2self of 10 bytes) that can be received from mac80211 to compute the extra_tx_headroom as 22 (32 - 10) bytes. When the wireless interface is part of bridge, this extra_tx_headroom requirement results in a memcpy in mac80211 (in function pskb_expand_head) for all the data frames needing L2 forwarding/bridging, when NET_SKB_PAD is defined as 32. This patch reduces the extra_tx_headroom by 8 bytes so that memcpy of data frames in mac80211 is avoided in this case. The resize will be required in driver for frames with 802.11 header size of less than 18 bytes. Signed-off-by:

Check status bits with mutex taken, because when we wait for mutex unlock, status can change. Patch should also make remaining sync commands be send with priv->mutex taken. That will prevent execute these commands when we are currently reset firmware, what could possibly cause troubles. Signed-off-by:

We mark command as huge by using meta->flags from other (non huge) command, but flags can be possibly overridden, when non huge command is enqueued, what can lead to: WARNING: at lib/dma-debug.c:696 dma_debug_device_change+0x1a3/0x1f0() DMA-API: device driver has pending DMA allocations while released from device [count=1] To fix introduce additional CMD_MAPPED to mark command as mapped and serialize iwl_enqueue_hcmd() with iwl_tx_cmd_complete() using hcmd_lock. Serialization will also fix possible race conditions, because q->read_ptr, q->write_ptr are modified/used in parallel. Do not change callback, I did (and fixed) that mistake in iwlagn. Signed-off-by:

Since commit f844a709 Author: Stanislaw Gruszka <sgruszka@redhat.com> Date: Fri Jan 28 16:47:44 2011 +0100 iwlwifi: do not set tx power when channel is changing we set device tx power during initialization to priv->tx_power_next, which itself is initialized to minimum power. That changed default behaviour of driver. Previously we initialized device to transmit at maximum available power by default. Patch change again to previous behaviour and cleanup tx power initialization. Fortunately this is not critical fix, as mac80211 layer setup tx power lately to 14dB, hence device does not operate at minimal transmit power all the time. Signed-off-by:
