This patch converts the remaining calls to use the work queue. In

Alex Romosan reported that since the mac80211 changes in
"mac80211: start auth/assoc timeout on frame status" and
the subsequent fixes in "mac80211: fix auth/assoc timeout
handling" (commits 1672c0e319 and 89afe614c0) there's
sometimes an issue connecting to a 5 GHz network with the
iwlwifi DVM driver.
The reason appears to be that since these commits any bad
TX status makes mac80211 immediately try again, causing
all of the authentication attempts to be quickly rejected
by the firmware as it hasn't heard a beacon yet. Before,
it would wait for the timeout regardless of status.
To fix this, invoke the passive-no-RX workaround when not
associated yet as well. This will cause the first frame
to get lost, but then the driver will stop the queues and
the second attempt will only be transmitted after hearing
a beacon, thus delaying it appropriately to not make the
firmware reject it again.

<http://marc.info/?l=linux-wireless&m=136381302428113>

according to Adrian Chadd is: "... notoriously unreliable and

Fix settings not being applied when the device is idle and the firmware
gets reloaded (because of changing from STA to AP mode). This caused
the device using the wrong channel (and likely band), e.g. a 5 GHz only
card still defaulted to channel 6 in the 2.4 GHz band when left
unconfigured.
This issue was always present, but only made visible with "mwl8k: Do not
call mwl8k_cmd_set_rf_channel unconditionally" (0f4316b9), since before
that the channel was (re-)configured at the next _config call even when
it did not change from the mac80211 perspective.

bigger than s8 can hold. We have for example:

formula. If poll_results[j] is small enough (it usually is) we treat

0xE8 - 0x1 = 0xE7, which is not 231 but -25.

Intermittently, b43 will report "Out of order TX status report on DMA ring".
When this happens, the driver must be reset before communication can resume.
The cause of the problem is believed to be an error in the closed-source
firmware; however, all versions of the firmware are affected.
This change uses the observation that the expected status is always 2 less
than the observed value, and supplies a fake status report to skip one
header/data pair.
Not all devices suffer from this problem, but it can occur several times
per second under heavy load. As each occurence kills the unmodified driver,
this patch makes if possible for the affected devices to function. The patch
logs only the first instance of the reset operation to prevent spamming
the logs.

This patch is a bug fix for an issue wherein power save was not
working for PCIe. This happens because for processing power save
sleep confirm command we pull skb so that skb->data points ahead
of interface header. We use same skb to get other cmda responses
as well. So if we don't push skb after processing cmd response,
it results into reduction in skb->len and finally skb->len reaches
zero. This causes failure in processing sleep command response.
Fix this by pushing skb by INTF_HEADER_LEN at the end of command
response processing.

Accumulate the total number of sent packets per-link to find out how far
the encryption sequence number has progressed. Use this number as the
initial security sequence number after recovery.
This consolidates security sequence handling for both chip families, as
we no longer have to rely on 12xx specific Tx completion.
A fortunate side effect of this is correct management of seq numbers for
AP roles and multi-role scenarios.
When a link is removed we save the last seq number on a persistent part
of the wlvif. This helps the data survive through recoveries/suspends,
which also entail changes in the hlid of the link.
This functionality is STA only currently.

rt2800 hardware sometimes reorders tx frames when transmitting to
multiple BA enabled STAs concurrently.
For example a tx queue
[ STA1 | STA2 | STA1 | STA2 ]
can result in the tx status reports
[ STA1 | STA1 | STA2 | STA2 ]
when the hw decides to put the frames for STA1 in one AMPDU.
To mitigate this effect associate the currently processed tx status
to the first frame in the tx queue with a matching wcid.
This patch fixes several problems related to incorrect tx status
reporting. Furthermore the tx rate selection is much more stable when
communicating with multiple STAs.

The commit 'ath9k_hw: fix calibration issues on chainmask that don't

for the duration of the calibration, but the revert to user
configuration in the reset path runs too early.
That causes some issues with limiting the number of antennas (including
spurious failure in hardware-generated packets).
Fix this by reverting the chainmask after the essential parts of the
calibration that need the workaround, and before NF calibration is run.

Either first 3 bytes of the first received tcp segment or last one
over MTU size file can be loss due to the byte alignment problem.
Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header
alignment' in the patch "Fix buffer alignment for scatter-gather
I/O"(1df94a857), there exists the bytes loss issue which means that it will be
truncated 3 bytes in the transmitted file contents if a file which has over MTU
size is transferred through TCP/IP stack. It doesn't look like TCP/IP stack
bug of 3.5 or the latest version of kernel but the byte alignment issue. This
patch is to use the roundup() function for the byte alignment rather than the
predefined ATH6KL_HTC_ALIGN_BYTES.

Dan found a check from ath6kl_rx() which doesn't make any sense at all:
" 1327 if (status || !(skb->data + HTC_HDR_LENGTH)) {
^^^^^^^^^^^^^^^^^^^^^^^^^^
skb->data is a pointer. This pointer math is always going to be false.
Should it be testing "packet->act_len < HTC_HDR_LENGTH" or something?"
I don't know what the check really was supposed to do, but I think Dan's guess
is right. Fix it accordingly.

Now all log messages are sent through the tracing infrastruture as well.
Tracing point doesn't follow debug_mask module parameter, instead it sends
all debug messages, so once you enable ath6kl_log_dbg tracing point you will
get a lot of messages. Needs to be discussed if this is sensible or not.
The overhead should be small enough and we anyway include debug level as
well so it's easy to filter in user space.
I wasn't really sure what to do with ath6kl_dbg_dump() and for now decided
that it also sends the buffer to user space. But most likely in the future
ath6kl_dbg_dump() should go away in favor of using proper tracing points, but
we will see.

Add a tracing point for hif irq and dump the register content to user space.
This is in hif.c as we could use the same code also with SPI but, as ath6kl
doesn't SPI and most likely never will be, this is used just by SDIO so
name the trace point as ath6kl_sdio_irq to make it easier to manage filters.
