Dean Nelson 0d6ab58da0 atl1e: return PCI_ERS_RESULT_DISCONNECT on permanent failure
PCI drivers that implement the struct pci_error_handlers' error_detected
callback should return PCI_ERS_RESULT_DISCONNECT if the state passed in is
pci_channel_io_perm_failure. This patch fixes the issue for atl1e.

Peter P Waskiewicz Jr 0a924578bc ixgbe: Fix RSC completion delay causing Rx interrupts to stop
When a user disables interrupt throttling with ethtool on 82599 devices,
the interrupt timer may not be re-enabled if hardware RSC is running.  The
RSC completions in hardware don't complete before the next ITR event tries
to fire, so the ITR timer never gets re-armed.  This patch increases the
amount of time between interrupts when throttling is disabled (rx-usecs =
0) when the hardware RSC deature is enabled.

Wey-Yi Guy 1e4247d457 iwlwifi: debugFs to enable/disable HT40 support
Add debugfs file to enable/disable HT40(40MHz) channel support.
By default, 40MHz is supported if AP can support the function.

By echo "1" to "disable_ht40" file, iwlwifi driver will disable the
40MHz support and only allow 20MHz channel.

Because the information exchange happen during association time,
so enable/disable ht40 channel only can be performed when it is not
associated with AP.

Roel Kluin 57921c312e libertas: Read buffer overflow
Several arrays were read before checking whether the index was within
bounds. ARRAY_SIZE() should be used to determine the size of arrays.

rates->rates has an arraysize of 1, so calling get_common_rates()
with a rates_size of MAX_RATES (14) was causing reads out of bounds.

tmp_size can increment at most to (ARRAY_SIZE(lbs_bg_rates) - 1) *
(*rates_size - 1), so that should be the number of elements of tmp[].

A goto can be eliminated: ret was already set upon its declaration.

Johannes Berg c2acea8e9b iwlwifi: fix up command sending
The current command sending in iwlwifi is a bit of a mess:
 1) there is a struct, iwl_cmd, that contains both driver
    and device data in a single packed structure -- this
    is very confusing
 2) the on-stack data and the command metadata share a
    structure by embedding the latter in the former, which
    is also rather confusing because it leads to weird
    unions and similarly odd constructs
 3) each txq always has enough space for 256 commands,
    even if only 32 end up being used

This patch fixes these things:
 1) rename iwl_cmd to iwl_device_cmd and keep track of
    command metadata and device command separately, in
    two arrays in each tx queue
 2) remove the 'meta' member from iwl_host_cmd and only
    put in the required members
 3) allocate the cmd/meta arrays separately instead of
    embedding them into the txq structure

Thermal Throttling feature is used to put NIC into low power state when

Two Thermal Throttling Management Methods; this patch introduce the
Legacy Thermal Management:

   IWL_TI_1: high temperature detect, low power state
   IWL_TI_2: higher temperature detected, lower power state
   IWL_TI_CT_KILL: critical temperature detected, lowest power state

Once get into CT_KILL state, uCode go into sleep, driver will stop all
the active queues, then move to IWL_TI_CT_KILL state; also set up 5
seconds timer to toggle CSR flag, uCode wake up upon CSR flag change,
then measure the temperature.
If temperature is above CT_KILL exit threshold, uCode go backto sleep;
if temperature is below CT_KILL exit threshold, uCode send Card State
Notification response with appropriate CT_KILL status flag, and uCode
remain awake, Driver receive Card State Notification Response and update
the card temperature to the CT_KILL exit threshold.

Johannes Berg 3fa52056f3 mac80211: fix PS-poll response, race
When a station queries us for a PS-poll response, we wrongly
queue the frame on the virtual interface's queue rather than
the pending queue.

Additionally, fix a race condition where we could potentially
send multiple frames to the sleeping station due to using a
station flag rather than a packet flag. When converting to a
packet flag, we can also convert p54 and remove the filter
clearing we added for it.

(Also remove a now dead function)

rt2x00dev->default_ant should be initialized once by the driver,
and should not be changed afterwards. Because rt2x00lib_config_antenna()
was using a reference to the struct antenna_setup it actually had the oppurtunity
to change the default antenna setting and it actually did that during the validation.

Instead of passing a pointer to antenna_setup the entire structure should be copied.

reinette chatre 45f5fa32b1 iwlagn: fix minimum number of queues setting
We need to provide a reasonable minimum that will result in a
working setup if used. Set minimum to be 10 to provide for
4 standard TX queues + 1 command queue + 2 (unused) HCCA queues +
4 HT queues (one per AC).

We allow the user to change the number of queues used via a module
parameter and use this minimum value to check if it is valid. Without
this patch a user can select a value for the number of queues that
will result in a failing setup.

Johannes Berg 3995bd9332 iwlwifi: fix TX queue race
I had a problem on 4965 hardware (well, probably other hardware too,
but others don't survive my stress testing right now, unfortunately)
where the driver was sending invalid commands to the device, but no
such thing could be seen from the driver's point of view. I could
reproduce this fairly easily by sending multiple TCP streams with
iperf on different TIDs, though sometimes a single iperf stream was
sufficient. It even happened with a single core, but I have forced
preemption turned on.

The culprit was a queue overrun, where we advanced the queue's write
pointer over the read pointer. After careful analysis I've come to
the conclusion that the cause is a race condition between iwlwifi
and mac80211.

mac80211, of course, checks whether the queue is stopped, before
transmitting a frame. This effectively looks like this:

        lock(queues)
        if (stopped(queue)) {
                unlock(queues)
                return busy;
	}
        unlock(queues)
        ...             <-- this place will be important
			    there is some more code here
        drv_tx(frame)

The driver, on the other hand, can stop and start queues, which does

        lock(queues)
        mark_running/stopped(queue)
        unlock(queues)

	[if marked running: wake up tasklet to send pending frames]

Now, however, once the driver starts the queue, mac80211 can see that
and end up at the marked place above, at which point for some reason the
driver seems to stop the queue again (I don't understand that) and then
we end up transmitting while the queue is actually full.

Now, this shouldn't actually matter much, but for some reason I've seen
it happen multiple times in a row and the queue actually overflows, at
which point the queue bites itself in the tail and things go completely
wrong.

This patch fixes this by just dropping the packet should this have
happened, and making the lock in iwlwifi cover everything so iwlwifi
can't race against itself (dropping the lock there might make it more
likely, but it did seem to happen without that too).

Since we can't hold the lock across drv_tx() above, I see no way to fix
this in mac80211, but I also don't understand why I haven't seen this
before -- maybe I just never stress tested it this badly.

With this patch, the device has survived many minutes of simultanously
sending two iperf streams on different TIDs with combined throughput
of about 60 Mbps.

Alexander Duyck 28fc06f58b igb: move all multicast addresses into multicast table array
This patch moves all of the multicast addresses out of the free Receive
address registers and instead programs them all into the multicast table
array.  As a result the multicast filtering may not be as precise, but it
also greatly reduces the overhead for multicast addresses.

Alexander Duyck 009bc06e53 igb: add completion timeout workaround for 82575/82576
The 82575 and 82576 hardware can both experience data corruption issues if
a pci-e completion arrives after the timeout value.  In order to avoid this
we need to increase the timeout value while pci-e master is disabled.

Alexander Duyck 12645a196e igb: do not overwrite EEPROM LED settings
The igb driver was overwritting the LED settings that were configured via
EEPROM.  This is not correct behavior as the LED settings are meant to be
configured by EEPROM and not changed.  This change removes the code that
was setting the LED behavior on the interface.
