c1f8ca1d83 rndis_wlan: fix buffer overflow in rndis_query_oid
rndis_query_oid overwrites *len which stores buffer size to return full size
of received command and then uses *len with memcpy to fill buffer with
command.

Ofcourse memcpy should be done before replacing buffer size.

3681165235 iwlwifi: remove reset led_tpt from iwl_leds_init()
Current blinking rate is calculated based on the difference between
current tx/rx byte counts and priv->led_tpt.

priv->led_tpt should not get reset in iwl_leds_init(), this function can be
called by bring interface "up" or "down", or when uCode sysassert occurred.
resetting the led_tpt parameter will introduce incorrect led blinking behavior.

c341ddb283 iwlwifi: print limited number of event log when uCode error
To help iwlagn uCode debugging, event log will dump to syslog when driver
detect uCode error occurred, but this only happen when compile with
CONFIG_IWLWIFI_DEBUG and debug flag is enabled; which is not always
the case. Also, there is another problem, if the flag is set, the entire
event log buffer will be dump to syslog, it can flood the syslog and
make it very difficult to debug the problem.

Change the default to only dump last 20 entries of event log to syslog
unless the following condition meets:
1. both compile with CONFIG_IWLWIFI_DEBUG and debug flag
is enabled, and then dump the entire event buffer to syslog.
2. dump event log request from debugfs

644c77f0cf iwlwifi: Tell the ucode immediately when association state changes
When we get a state change of associated or not, we need to tell the
ucode via the RX_ON command using the filter flags.  This will prevent
the ucode from sending any packets when not associated, specifically not
sending NULL QOS packets after a deauthentication which causes the AP to
repeatedly send deauth's in some situations.

74ba67edfc iwlagn: Use iwl_write8() for CSR_INT_COALESCING register
CSR_INT_COALESCING previously had only one, but now has two single-byte fields.
With only one single-byte field (lowest order byte) it was okay to write via
iwl_write32(), but now with two, an iwl_write32() to the lower order field
clobbers the other field (odd-address CSR_INT_PERIODIC_REG, offset 0x5), and an
iwl_write32() to CSR_INT_PERIODIC_REG could clobber the lowest byte of the
next-higher register (CSR_INT, offset 0x8).

Fortunately, no bad side effects have been produced by the iwl_write32()
usage, due to order of execution (low order byte was always written before
higher order byte), and the fact that writing "0" to the low byte of the
next higher register has no effect (only action is when writing "1"s).

Nonetheless, this cleans up the accesses so no bad side effects might occur
in the future, if execution order changes, or more bit fields get added to
CSR_INT_COALESCING.

Add some comments regarding periodic interrupt usage.

07681e211d b43: Rewrite DMA Tx status handling sanity checks
This rewrites the error handling policies in the TX status handler.
It tries to be error-tolerant as in "try hard to not crash the machine".
It won't recover from errors (that are bugs in the firmware or driver),
because that's impossible. However, it will return a more or less useful
error message and bail out. It also tries hard to use rate-limited messages
to not flood the syslog in case of a failure.

7351c6bd48 mac80211: request TX status where needed
Right now all frames mac80211 hands to the driver
have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set to
request TX status. This isn't really necessary, only
the injected frames need TX status (the latter for
hostapd) so move setting this flag.

The rate control algorithms also need TX status, but
they don't require it.

Also, rt2x00 uses that bit for its own purposes and
seems to require it being set for all frames, but
that can be fixed in rt2x00.

This doesn't really change anything for any drivers
but in the future drivers using hw-rate control may
opt to not report TX status for frames that don't
have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set.

c74ddfd5ea wl1251: allocate space for firmware with vmalloc()
Earlier firmware was stored to a memory area allocated with kmalloc()
but finding a a contiguous area of memory long enough for the firmware is
very difficult in certain cases. better to allocate the memory for firmware
with vmalloc() instead and use a small buffer for DMA transfers.

Thanks to Eero Tamminen for the idea.

d5da79ac1f wl1251: Implement delayed entry into ELP mode
Implement (slightly) delayed entry into ELP. This will cure several
problems:
  - It works around a firmware race condition if ELP is entered too fast
    after commands (resulting in ELP timeout -traces)
  - It will reduce the number of sleep-wake cycles between already
    scheduled events such as interrupts and tx, hence improving
    performance (less delay in switching between RX and TX)

15295380f4 ar9170: Add support for D-Link DWA 160 A2
At least two revisions of the D-Link DWA 160 exist, called A1 and A2. A1
(USB-ID 07d1:3c10) is already listed in usb.c as D-Link DWA 160A. A2
(USB-ID 07d1:3a09) works if added to ar9170_usb_ids. I didn't do much
testing until now, but I was able to connect to APs using WPA or WEP and
transmit data.

Summary:

* Add model revision number to the comment for D-Link DWA 160 A1 (07d1:3c10)
* Add support for D-Link DWA 160 A2 (07d1:3a09)

c951ad3550 mac80211: convert aggregation to operate on vifs/stas
The entire aggregation code currently operates on the
hw pointer and station addresses, but that needs to
change to make stations purely per-vif; As one step
preparing for that make the aggregation code callable
with the station, or by the combination of virtual
interface and station address.
