In status processing we'll need to find the context for a given frame, so add a context pointer to the TX info for each frame. Signed-off-by:

Since mac80211 doesn't currently enable/disable QoS per interface, we can't yet do it properly, but we can already prepare for it and move the QoS data and command ID into the context struct. Signed-off-by:

Johannes Berg authored
Some commands will have different command IDs for different contexts, so we need to store those IDs in the context structure and use them instead of hardcoding the commands. Signed-off-by:

The microcode tracks stations per context, so the driver needs to do that as well for adding, deleting and restoring them, especially in the implicit removal case when we send an RXON. Signed-off-by:

The broadcast station ID is per context, so add a variable for the ID in the context and use it everywhere we previously hardcoded it. Signed-off-by:

PAN capable microcode has a different queue assignment (not just more queues for PAN) due to the way multicast is handled for AP mode. Signed-off-by:
-
Johannes Berg authored
PAN ucode will require a different queue assignment, in particular queue 9 instead of 4 should be used for commands. This is required because the ucode will stop/start queues 4 and 8 depending on the PAN state, since queue 8 will be used for PAN multicast (after DTIM). Signed-off-by:

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. Signed-off-by:

Encounter compiler error when iwlwifi debugging support is disabled, fix it. This compiler error was introduced by the previous WiFi/BT coexist patchset. Signed-off-by:

When a mac80211-based driver advertises mesh mode support, this will be advertised to userspace. However, if mac80211 was compiled without mesh support, then that won't actually be true. Fix this by removing the bit for mesh if mesh isn't compiled in. Since this synchronizes what we advertise to cfg80211 and actually support, it means we can now rely on cfg80211's interface type checks and need not check again in mac80211. Signed-off-by:

This patch should fix the dodgy signal and noise value reports for most longbow (p54spi) users: e.g.: (an older tcpdump extract) > 2.0 Mb/s 2437 MHz (0x00a0) -49dB signal -41dB noise > 1.0 Mb/s 2437 MHz (0x00a0) 4dB signal -41dB noise The formula is taken from stlc45xx: http://gitorious.org/stlc45xx/mainline/blobs/master/stlc45xx.c#line1199Signed-off-by:

This patch fixes a potential crash (null-pointer de- reference) which was introduced in my previous patch: "mac80211: AMPDU rx reorder timeout timer" During a BA teardown, the pointer to the soon-to-be-gone tid_ampdu_rx element will be nullified. Therefore the release timer mechanism has to be careful not to accidentally access the item without any RCU protection. Signed-off-by:

commit 95a6ccbb46c70cff376684c752831c014c87029d Author: Johannes Berg <johannes.berg@intel.com> Date: Thu Aug 12 15:38:38 2010 +0200 cfg80211/mac80211: extensible frame processing introduced a netlink bug that caused parsing errors in userspace because it forgot to close a nesting, which would advertise a nesting length of zero to userspace, which then completely threw off parsing and led to Illegal nla->nla_type == 0 being printed by libnl.

During initialization each driver reads the default TX power for each individual channel. However mac80211 only accepts the maximum value (which is also handled as default value). As a result, the TX power of the device was being limited to the default value, which is often quite low compared to the real maximum acceptable value. This patch allows each driver to set the maximum value on a per-channel basis which is forwarded to mac80211. The default value will be preserved for now, in case we want to update mac80211 to differentiate between the maximum and default txpower. This fixes bug complaining about limited TX power values like: https://bugzilla.kernel.org/show_bug.cgi?id=16358Signed-off-by:

We missed a check for RF3052 in the config_channel configuration function. As a result the channel is not properly configured for RF3052 devices. This also requires rt2800_config_channel_rf3xxx to support 5GHz channels, so we must apply the TXPOWER_A_TO_DEV and TXPOWER_G_TO_DEV conversions during rt2800_config_channel() Signed-off-by:

The functions rt2800pci_enable_radio and rt2800usb_disable_radio are almost equal and can be merged into rt2800lib. This reduces the number of functions which must be exported from rt2800lib to the drivers at the same time. Also rt2800pci_disable_radio and rt2800usb_disable_radio are almost equal and can be merged into rt2800lib in a similar fashion. Signed-off-by:

The retry count for a frame is calculated by the realized MCS rate subtracting of the requested MCS rate. However during TX done reporting we accidently override the requested MCS rate with the realized MCS rate. This causes the retry count to be reset to 0 always, and feeding invalid rate information into minstrel_ht. Signed-off-by:

Q_INDEX_CRYPTO and ENTRY_OWNER_DEVICE_CRYPTO where initially added with the plan to implement hardware encryption for rt2500pci. However there are no plans to do so anymore as the crypto mechanism in rt2500pci is very different then any other Ralink device. So we can now safely remove the definitions, and don't think about this feature anymore. :) Signed-off-by:

All access to queue->entries through the Q_INDEX/Q_INDEX_DONE variables must be done using spinlock protection. It is best to manage this completely from rt2x00queue.c. For safely looping through all entries in the queue, the function rt2x00queue_for_each_entry is added which will walk from from a index range in a safe manner. This also fixes rt2x00usb which walked the entries list from 0 to length to kill each entry (killing entries must be done from Q_INDEX_DONE to Q_INDEX to enforce TX status reporting to occur in the correct order.

write_tx_desc shouldn't pass a rt2x00dev and skb pointer, instead it should use the same format as other TX frame callback functions, which is passing the data_entry pointer which contains all the information which is needed to work on a TX frame. Most callers of the kick_tx_queue and kill_tx_queue already have the data_queue pointer, so rather then sending the QID with the given function, when the driver requests a new pointer to the data_queue, it is more efficient to just send the data_queue pointer directly.

When aggregation is stopped again for some reason before the queue we selected has drained, we will currently leak the TX queue and keep it enabled for aggregation. Normally this doesn't happen, so the problem is rarely seen. Signed-off-by:

Current BT traffic load should based on the following conditions: 1. BT On/Off status 2. Channel announcement enable/disable 3. Curren traffic load report from uCode Need to modify rate scale to down-grade from MIMO to SISO if detected high BT traffic load. Also need to make sure not using chain "B" with high BT traffic or if it is in "full concurrency" mode. Signed-off-by:

bt config command need to send before the init calibration command, driver need to let uCode know that calibrations are being performed now in order to assure antenna is not being taken to BT use during radio/dsp reads/writes Also, bt_coex_priorty_table command need to be send right after the bt_config_command during init sequence.

Adding the bluetooth full concurrency support for WiFi/BT combo devices. Driver should configure uCode to operate in "full concurrency" mode (via LUT) if both conditions are met: - Antenna Coupling is more than 35dB - WiFi Channel Inhibition Request is hornored by BT Core Currently, there is no antenna coupling information provided by uCode; use module parameter to specified the antenna coupling in dB. When in "full concurrency" mode, driver need to download different LUT to uCode while sending bt configuration command; also, driver need to configure the device operate in 1x1 while in full concurrency mode.

When bluetooth indicated high load, we should use only antenna A in 2.4 GHz for management frames. Add this condition to iwl_toggle_tx_ant() to make sure it'll always be met. Note that scanning has a separate way of forcing the antenna, because we should scan on antenna A only regardless of BT traffic load. Signed-off-by:

IBSS doesn't allow for coexistence, so it should be disabled. Additionally, disable reacting to the BT profile notification when in IBSS mode, it likely won't be sent by the device to start with though. Also, in IBSS mode, BT coexistence isn't as fully-featured and we must use a single antenna only. So instead of peppering the code with new checks, simply pretend we are in high BT traffic load, which has the needed effect of disabling antenna B use. Signed-off-by:
