iwlagn: fix rts cts protection
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.

* We enable the driver to be backward compatible wrt API version. The

|
* on firmware version used.
|
|
|
|
|
*
|
|
|
|
|
* For example,
|

|

|
* if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
|
2010-10-06 23:10:00 +08:00

|
|

* Driver interacts with Firmware API version 1.

2008-12-03 04:14:06 +08:00
|
|
|
* }
|
|
|
|
|
*
|
|
|
|
|
* The ideal usage of this infrastructure is to treat a new ucode API
|
|
|
|
|
* release as a new hardware revision. That is, through utilizing the
|
|
|
|
|
* iwl_hcmd_utils_ops etc. we accommodate different command structures

iwlwifi: reliable entering of critical temperature state
When uCode detects critical temperature it should send "card state
notification" interrupt to driver and then shut itself down to prevent
overheating. There is a race condition where uCode shuts down before it
can deliver the interrupt to driver.
Additional method provided here for driver to enter CT_KILL state based
on temperature reading.
How it works:
Method 1:
If driver receive "card state notification" interrupt from uCode; it
enters "CT_KILL" state immediately
Method 2:
If the last temperature report by Card reach Critical temperature,
driver will send "statistic notification" request to uCode to verify the
temperature reading, if driver can not get reply from uCode within
300ms, driver will enter CT_KILL state automatically.
Method 3:
If the last temperature report by Card did not reach Critical
temperature, but uCode already shut down due to critical temperature.
All the host commands send to uCode will not get process by uCode;
when command queue reach the limit, driver will check the last reported
temperature reading, if it is within pre-defined margin, enter "CT_KILL"
state immediately. In this case, when uCode ready to exit from "CT_KILL" state,
driver need to restart the adapter in order to reset all the queues and
resume normal operation.
One additional issue being address here, when system is in CT_KILL
state, both tx and rx already stopped, but driver still can send host
command to uCode, it will flood the command queue since card was not
responding; adding STATUS_CT_KILL flag to reject enqueue host commands
to uCode if it is in CT_KILL state, when uCode is ready to come out of
CT_KILL, driver will clear the STATUS_CT_KILL bit and allow enqueue the host
commands to uCode to recover from CT_KILL state.
