Marty Faltesek f67b107d4c ath10k: cache calibration data when the core is stopped
Commit 0b8e3c4ca2 ("ath10k: move cal data len to hw_params") broke retrieving
the calibration data from cal_data debugfs file. The length of file was always
zero. The reason is:

    static ssize_t ath10k_debug_cal_data_read(struct file *file,
                                          char __user *user_buf,
                                          size_t count, loff_t *ppos)
    {
        struct ath10k *ar = file->private_data;
        void *buf = file->private_data;

This is obviously bogus, private_data cannot contain both struct ath10k and the
buffer. Fix it by caching calibration data to ar->debug.cal_data. This also
allows it to be accessed when the device is not active (interface is down).

The cal_data buffer is fixed size because during the first firmware probe we
don't yet know what will be the lenght of the calibration data. It was simplest
just to use a fixed length. There's a WARN_ON() in
ath10k_debug_cal_data_fetch() if the buffer is too small.

Tested with qca988x and firmware 10.2.4.70.56.

Larry Finger cf4747d753 rtlwifi: Fix regression caused by commit d86e647688
In commit d86e647688 ("rtlwifi: rtl818x: constify local structures"),
the configuration struct for most of the drivers was changed to be
constant. The problem is that five of the modified drivers need to be
able to update the firmware name based on the exact model of the card.
As the file names were stored in one of the members of that struct,
these drivers would fail with a kernel BUG splat when they tried to
update the firmware name.

Rather than reverting the previous commit, I used a suggestion by
Johannes Berg and made the firmware file name pointers be local to
the routines that update the software variables.

The configuration struct of rtl8192cu, which was not touched in the
previous patch, is now constantfied.

Jes Sorensen 29d5e6fbd6 rtl8xxxu: Fix rtl8192eu driver reload issue
The 8192eu suffered from two issues when reloading the driver.

The same problems as with the 8723bu where REG_RX_WAIT_CCA bits 22 and
23 didn't get set in rtl8192e_enable_rf().

In addition it also seems prone to issues when setting REG_RF_CTRL to
0 intead of just disabling the RF_ENABLE bit. Similar to what was
causing issues with the 8188eu.

With this patch I can successfully reload the driver and reassociate
to an APi with an 8192eu dongle.

The generic disable_rf() function clears bits 22 and 23 in

A device running without RX package aggregation could return more data
in the USB packet than the actual network packet. In this case we
could would clone the skb but then determine that that there was no
packet to handle and exit without freeing the cloned skb first.

This has so far only been observed with 8188eu devices, but could
affect others.

Rajkumar Manoharan 0628467f97 ath10k: fix copy engine 5 destination ring stuck
Firmware is running watchdog timer for tracking copy engine ring index
and write index. Whenever both indices are stuck at same location for
given duration, watchdog will be trigger to assert target. While
updating copy engine destination ring write index, driver ensures that
write index will not be same as read index by finding delta between these
two indices (CE_RING_DELTA).

HTT target to host copy engine (CE5) is special case where ring buffers
will be reused and delta check is not applied while updating write index.
In rare scenario, whenever CE5 ring is full, both indices will be referring
same location and this is causing CE ring stuck issue as explained
above. This issue is originally reported on IPQ4019 during long hour stress
testing and during veriwave max clients testsuites. The same issue is
also observed in other chips as well. Fix this by ensuring that write
index is one less than read index which means that full ring is
available for receiving data.

Ethernet type. When deleting flowring we have to use freeing function

Rafał Miłecki 2f0e56fa37 brcmfmac: replace WARNING on timeout with a simple error message
Even with timeout increased to 950 ms we get WARNINGs from time to time.
It mostly happens on A-MPDU stalls (e.g. when station goes out of
range). It may take up to 5-10 secods for the firmware to recover and
for that time it doesn't process packets.

It's still useful to have a message on time out as it may indicate some
firmware problem and incorrect key update. Raising a WARNING however
wasn't really that necessary, it doesn't point to any driver bug anymore
and backtrace wasn't much useful.

Chipset from QCA99X0 onwards (QCA99X0, QCA9984, QCA4019 & future)
rx_hdr_status is not padded to align in 4-byte boundary. Define a
new hw_params field to handle different alignment behaviour between
different hw. This patch fixes improper retrieval of rfc1042 header

As soon as debugging is turned on, the logs are filled with messages

output is not needed. In fact, there will be a report if the status is

It's been observed that in a corner case mwifiex_usb_tx_complete()
gets called before we exit from mwifiex_usb_host_to_card() after
submitting the urb. 'data_sent' flag remains set in this case. It
blocks further Tx packets and triggers watchdog timeout.

In mwifiex_usb_tx_complete(), we are updating port->block_status first
