5afa5aa796 ath6kl: get rid of AR_DBG_LVL_CHECK()
We don't need it as debug calls already have a log level and compiler
should be smart enough to optimise away the code when ath6kl debug code
is not enabled. Also it makes it easier to abstract core code to
ath6kl_core.ko.

In ath6kl_dump_registers() I had to change the debug level from ANY to IRQ
as I removed the AR_DBG_LVL_CHECK() check before calling the function.

45eaa78f75 ath6kl: create core.c
Currently core functions are spread between various files, group all
the functions into file and rename the functions to follow the style
used elsewhere in the driver. This will make it easier to a separate core
module.

Also fix a bug where wiphy is freed too early.

e572602884 ath6kl: fix uninitialized warning in ath6kl_process_uapsdq()
Before I commited patch c1762a3fe ("ath6kl: Add support for uAPSD") I
did a minor change how up variable is initialised in
ath6kl_process_uapsdq(). But I was sloppy and caused this compiler
warning:

c1762a3fe1 ath6kl: Add support for uAPSD
* A new APSD power save queue is added in the station structure.
* When a station has APSD capability and goes to power save, the frame
  designated to the station will be buffered in APSD queue.
* When the host receives a frame which the firmware marked as trigger,
  host delivers the buffered frame from the APSD power save queue.
  Number of frames to deliver is decided by MAX SP length.
* When a station moves from sleep to awake state, all frames buffered
  in APSD power save queue are sent to the firmware.
* When a station is disconnected, all frames bufferes in APSD power save
  queue are dropped.
* When the host queues the first frame to the APSD queue or removes the
  last frame from the APSD queue, it is indicated to the firmware using
  WMI_AP_APSD_BUFFERED_TRAFFIC_CMD.

8232736dab ath6kl: Fix listen interval handling
This patch addresses a few problems with the commit:

"ath6kl: Implement support for listen interval from userspace"

* The debugfs file required for reading/writing the listen interval
  wasn't created. Fix this.

* The interface index was being hardcoded to zero. Fix this.

* Two separate parameters, "listen_interval_time and listen_interval_beacons"
  were being used. This fails to work as expected because the FW assigns
  higher precedence to "listen_interval_beacons" and "listen_interval_time"
  ends up being never used at all.

  To handle this, fix the host driver to exclusively use listen interval
  based on units of beacon intervals.

To set the listen interval, a user would now do something like this:

echo "10" > /sys/kernel/debug/ieee80211/*/ath6kl/listen_interval

77e1e438cb r6040: fix typo in use of MCR0 register bits
Commit 4e16d6ebd6 (r6040: define more MCR0
register bits) added #define values for MCR0 register bits and converted
uses of hardcoded magic values to uses of these defines.

However, one of the conversions looks suspicious:

 #define MCR0		0x00	/* Control register 0 */
+#define  MCR0_RCVEN	0x0002	/* Receive enable */
+#define  MCR0_XMTEN	0x1000	/* Transmission enable */

 	/* Init RDC private data */
-	lp->mcr0 = 0x1002;
+	lp->mcr0 = MCR0_XMTEN | MCR0;

I believe what was meant here was MCR0_XMTEN | MCR0_RCVEN, which makes
sense and matches the original values.

23021c2105 cnic: Improve error recovery on bnx2x devices
When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages.  As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.

To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.

Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.
