iwlwifi: pcie: don't panic on host commands in iwldvm
None of the devices supported by iwldvm have support for
shadow registers. This means that we wake the NIC
when we increment the write pointer on Tx ring.
This happened even before my bad commit mentionned below.
Since my commit below, we wake up the NIC when we put a
host command on the ring regardless of shadow register
support. This means that in iwldvm (when the NIC doesn't
support shadow register), we wake up the NIC twice:
pcie_enqueue_hcmd:
wake up the NIC
iwl_pcie_txq_inc_wr_ptr:
wake up the NIC - no shadow reg support
Since waking up the NIC means that we need to acquire a
spinlock, this obviously leads to a recursive spinlock
and hence a freeze.

b43: Fix lockdep splat
In https://bugzilla.kernel.org/show_bug.cgi?id=67561, a locking dependency is reported
when b43 is used with hostapd, and rfkill is used to kill the radio output.
The lockdep splat (in part) is as follows:
======================================================
[ INFO: possible circular locking dependency detected ]
3.12.0 #1 Not tainted
-------------------------------------------------------
rfkill/10040 is trying to acquire lock:
(rtnl_mutex){+.+.+.}, at: [<

but task is already holding lock:

--snip--
Chain exists of:
rtnl_mutex --> misc_mtx --> rfkill_global_mutex
The fix is to move the initialization of the hardware random number generator
outside the code range covered by the rtnl_mutex.

iwlwifi: mvm: don't set the drain bit when we flush the AP station
When we disassociate in managed mode, we flush the queues
after mac80211 has already removed the station.
During that time, the pointer to ieee80211_sta to the
fw_id_to_mac_id map is -EINVAL. In that case we should not
set the station as being drained when the last Tx of this
station has exited the shared Tx queue since we are
flushing all the queues anyway.
The draining logic is meant to be used in GO / AP mode only.
In GO / AP mode, we set -EBUSY in the fw_id_to_mac_id map.
This is why testing the ieee80211_sta pointer in the
fw_id_to_mac_id map with IS_ERR isn't enough to set the
station as draining, we need to check that it is -EBUSY.

mac80211: release multiple ACs in uAPSD, fix more-data bug
When a response for PS-Poll or a uAPSD trigger frame is sent, the
more-data bit should be set according to 802.11-2012 11.2.1.5 h),
meaning that it should indicate more data on the relevant ACs
(delivery-enabled or nondelivery-enabled for uAPSD or PS-Poll.)
In, for example, the following scenario:
* 1 frame on VO queue (either in driver or in mac80211)
* at least 1 frame on VI queue (in the driver)
* both VO/VI are delivery-enabled
* uAPSD trigger frame received
The more-data flag to the driver would not be set, even though
it should be.
While fixing this, I noticed that we should really release frames
from multiple ACs where there's data buffered in the driver for
the corresponding TIDs.
To address all this, restructure the code a bit to consider all
ACs if we only release driver frames or only buffered frames.
This also addresses the more-data bug described above as now the
TIDs will all be marked as released, so the driver will have to
check the number of frames.
While at it, clarify some code and comments and remove the found
variable, replacing it with the appropriate sw/hw release check.

could have been updated when a scan is issued. Since a
channel change involves flushing the existing packets
in the RX queue before a chip-reset is done, they would
be processed using the wrong band/channel information.
To avoid this, use the current channel information
maintained in the driver.

If cfgdata length exceeds the command buffer size we will end up
getting buffer overflow problem. Fix it by checking the buffer
size less the command header length.

wil6210: prefetch head of packet
As soon as skb is ready to be reaped, prefetch 1-st cache line.
This accelerates data access that is performed later, during the
packet classification by the driver and IP stack.

wil6210: interrupt moderation
Use hardware capabilities to limit IRQ generation to about 15 per msec
It corresponds to about 7 packets/IRQ when running iperf with default
parameters at 1.3Gbps
Do not enable this feature in the sniffer (monitor) mode, because
interrupt moderation cause timestamp accuracy deterioration.
For the sniffer flow, it is important to get precise timestamp.
