Johannes Berg 13bb9483e1 iwlwifi: prepare for PAN queue/fifo assignment
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).

Johannes Berg 246ed35522 iwlwifi: initial contextification
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.

Wey-Yi Guy da5dbb9715 iwlagn: set traffic load based on multiple factors
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.

In current implementation, stuck queue timer is fixed to 1 second. Add
debugfs file to modify the timer to enhance the flexibility:

Set the monitor_period as following:
   0: disable stuck queue force reset function
   1 - 60000: monitor period (1 - 60 second)

Wey-Yi Guy bee008b783 iwlwifi: add bt full concurrency support
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.

Johannes Berg 59079949fa iwlagn: disable gen2b BT coexistence in IBSS
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.

Johannes Berg 97359d1235 mac80211: use cipher suite selectors
Currently, mac80211 translates the cfg80211
cipher suite selectors into ALG_* values.
That isn't all too useful, and some drivers
benefit from the distinction between WEP40
and WEP104 as well. Therefore, convert it
all to use the cipher suite selectors.

Wey-Yi Guy 6555063666 iwlwifi: add support for device tx flush request
"Flush" request can come from two different sources, it can either from
mac80211, or from device when the operation is needed. Here
adding the support for device issue "flush" request.

When receive tx complete with status is TX_STATUS_FAIL_RFKILL_FLUSH,
issue REPLY_TXFIFO_FLUSH command to uCode to flush out all the tx frames
in queues.

In this condition, since mac80211 has no knowledge of "flush" operation,
driver need to stop all the tx queues and wait for the operation
completed before wake up the queues for frames transmission.
