In accordance to the latest mgmt API specification the opcode comes
first and then the status.

This patch adds interleaved discovery support to MGMT Start
Discovery command.
In case interleaved discovery is not supported (not a dual mode
device), we perform BR/EDR or LE-only discovery according to the
device capabilities.

This patch merges DISCOVERY_INQUIRY and DISCOVERY_LE_SCAN states
into a new state called DISCOVERY_FINDING.
From the discovery perspective, we are pretty much worried about
to know just if we are finding devices than what exactly phase of
"finding devices" (inquiry or LE scan) we are currently running.
Besides, to know if the controller is performing inquiry or LE scan
we should check HCI_INQUIRY or HCI_LE_SCAN bits in hdev flags.
Moreover, merging this two states will simplify the discovery state
machine and will keep interleaved discovery implementation simpler.

This patch does some code refactoring in start_discovery function
in order to prepare it for interleaved discovery support.
MGMT_ADDR_* macros were moved to hci_core.h since they are now used
to define discovery type macros.
Discovery type macros were defined according to mgmt-api.txt
specification:
Possible values for the Type parameter are a bit-wise or of the
following bits:
1 BR/EDR
2 LE Public
3 LE Random
By combining these e.g. the following values are possible:
1 BR/EDR
6 LE (public & random)
7 BR/EDR/LE (interleaved discovery)

Rate control algorithms are supposed to stop processing when they
encounter a rate with the index -1. Checking for rate->count not being
zero is not enough.
Allowing a rate with negative index leads to memory corruption in
ath_debug_stat_rc().

Driver maintains different flags for WEP, WPA, WPA2 security modes.
Appropriate flag is set using security information provided in
connect request. mwifiex_is_network_compatible() routine uses them
to check if driver's setting is compatible with AP. Association is
aborted if the routine fails.
For some corner cases, it is observed that association is failed
even for valid security information based on association history.
This patch fixes the problem by clearing previous security setting
during each association.
We should set WEP key provided in connect request as default tx key.
This missing change is also added here.

There are situations where we don't have the
necessary rate control information yet for
station entries, e.g. when associating. This
currently doesn't really happen due to the
dummy station handling; explicitly disabling
rate control when it's not initialised will
allow us to remove dummy stations.

__cancel_delayed_work() is being used in some paths where we cannot
sleep waiting for the delayed work to finish. However, that function
might return while the timer is running and the work will be queued
again. Replace the calls with safer cancel_delayed_work() version
which spins until the timer handler finishes on other CPUs and
cancels the delayed work.

This issue has been brought up earlier here:
https://lkml.org/lkml/2011/5/21/127
The issue appears to be the rfcomm_session_put in rfcomm_recv_ua. This
operation doesn't seem be to required as for the non-initiator case we
have the rfcomm_process_rx doing an explicit put and in the initiator
case the last dlc_unlink will drive the reference counter to 0.
There have been several attempts to fix these issue:
6c2718d Bluetooth: Do not call rfcomm_session_put() for RFCOMM UA on closed socket
683d949 Bluetooth: Never deallocate a session when some DLC points to it
but AFAICS they do not fix the issue just make it harder to reproduce.

Since bluetooth uses multiple protocols types, to avoid lockdep
warnings, we need to use different lockdep classes (one for each
protocol type).
This is already done in bt_sock_create but it misses a couple of cases
when new connections are created. This patch corrects that to fix the
following warning:

After moving L2CAP timers to workqueues l2cap_set_timer expects timeout
value to be specified in jiffies but constants defined in miliseconds
are used. This makes timeouts unreliable when CONFIG_HZ is not set to
1000.
__set_chan_timer macro still uses jiffies as input to avoid multiple
conversions from/to jiffies for sk_sndtimeo value which is already
specified in jiffies.

Commit 330605423c fixed l2cap conn establishment for non-ssp remote
devices by not setting HCI_CONN_ENCRYPT_PEND every time conn security
is tested (which was always returning failure on any subsequent
security checks).
However, this broke l2cap conn establishment for ssp remote devices
when an ACL link was already established at SDP-level security. This
fix ensures that encryption must be pending whenever authentication
is also pending.

the intilization of this read/write lock happens via the path
ieee80211_led_init (->) led_trigger_register, but we are doing
'ieee80211_led_init' after 'ieeee80211_if_add' where we

Some devices (iwl5100) cannot connect to zd1211rw based AP. It appears that
zd1211 firmware messes up duration_id field if it is not set to zero by driver.
Sniffing traffic shows that zd1211 is transmitting frames with duration_id bits
14 and 15 set and other bits appearing random. Setting duration_id at driver to
zero results zd1211 outputting sane duration_id. This means that firmware is
setting correct values itself and expects duration_id to be zero in first
place.
Looking at vendor driver shows that only PSPoll frames have duration_id set by
driver, for other frames duration_id left zero.

The brcmsmac driver is now using the bcma SPROM CRC check, which does
not recognize all chipsets that were functional prior to the switch. In
particular, the current code bails out on odd CRC errors in recent
Macbooks. This patch ignores those errors, with the argument that an
unrecognized SPROM should be treated similarly to a non-existing one.

commit adb5066 "ath9k_hw: do not apply the 2.4 ghz ack timeout
workaround to cts" reduced the hardware CTS timeout to the normal
values specified by the standard, but it turns out while it doesn't
need the same extra time that it needs for the ACK timeout, it
does need more than the value specified in the standard, but only
for 2.4 GHz.
This patch brings the CTS timeout value in sync with the initialization
values, while still allowing adjustment for bigger distances.

commit b4a82a0 "ath9k_hw: fix interpretation of the rx KeyMiss flag"
fixed the interpretation of the KeyMiss flag for keycache based lookups,
however WEP encryption uses a static index, so KeyMiss is always asserted
for it, even though frames are decrypted properly.
Fix this by clearing the ATH9K_RXERR_KEYMISS flag if no keycache based
lookup was performed.

Currently even if association is failed "iw link" shows some
information about connected BSS and "Tx timeout" error is seen in
dmesg log.
This patch fixes below issues in the code to handle assoc failure
case correctly.
1) "status" variable in mwifiex_wait_queue_complete() is not
correctly updated. Hence driver doesn't inform cfg80211 stack
about association failure.
2) During association network queues are stopped but carrier is
not cleared, which gives Tx timeout error in failure case

The device seems to survive the issue, so no need to flood the logs
about it...

The current code checks for stored_mpdu_num > 1, causing
the reorder_timer to be triggered indefinitely, but the
frame is never timed-out (until the next packet is received)

In my AMPDU rework, I rely on the sequence numbers of frames. But
I didn't check that the frame has a valid tid before updating the
tracking counters. As a result, the Tx queues were stalled. People
who hit this bug saw that we simply didn't let any data out.
This bug was introduced in 3.3.
This patch fixes that and checks that the frame is a QoS frame before
looking at its tid and changing the counters.

ssb supports one extra device on the cardbus. This results in two
devices in total, one beeing the host controller itself and the other
the external device connected to the hostcontroller over cardbus.
This makes the cardbus slot work on the Linksys WRT150N.
