fe5d96246e orinoco_usb: Fix broken firmware load error checking
The check of ezusb_firmware_download() return value (added by commit
488ec87803) is broken because
ezusb_firmware_download() returns 1 on success.
This causes the driver not to work with the following error:
orinoco_usb: probe of 3-3:1.0 failed with error -14

Check the return value only for negative values.

This fix should be applied to -stable kernels too.

e515e9cb64 ath9k: non-functional: calculate DFS pulse interval per-wiphy
Systems with multiple DFS channel detectors need to track
timestamp of previous pulse per instance to display the
correct pulse interval.

Since the interval value is used for debug printing only,
this is a non-functional modification.

f9ac71bfcc mac80211: fix vif name tracing
If sdata doesn't have a valid dev (e.g. in case of monitor
vif), the vif_name field was initialized with (a length of)
some short string, but later was set to a different,
potentially larger one.

This resulted in out-of-bounds write, which usually
appeared as garbage in the trace log.

Simply trace sdata->name, as it should always have the
correct name for both cases.

4a817aa78f mac80211: allow VHT with peers not capable of 40MHz
There are two (related) issues with this.

One case, reported by Michal, is related to hostap: it unsets the
20/40 capability bit for stations that associate when it's in 20
MHz mode.

The other case, reported by Eyal, is that some APs like Netgear
R6300v2 and probably others based on the BCM4360 chipset can be
configured for doing VHT at 20Mhz. In this case the beacon has
a VHT IE but the HT cap indicates transmitter only support 20Mhz.

In both of these cases, we currently avoid VHT and use only HT
this means we can't use the highest rates (MCS8), so fixing this
leads to throughput improvements.

has been received with short preamble.

It simply checks for the "splcp" flag in the RX status
descriptor, and eventually set RX_FLAG_SHORTPRE in mac80211
rx status structure.

552a515707 ath9k: Allow platform override without EEPROM override
Add a new platform data flag "use_eeprom" that indicates that the eeprom
found on the card itself should be used instead of the one present in
the platform data.

This allows to override the MAC address of a PCI card while preserving
the eeprom data from the card itself.

The default behavior is preserved.

79ff434612 mwifiex: disable TDLS link upon tear down event
This patch adds code to disable TDLS link upon reception of TDLS
teardown event from peer. Teardown event can happen either
because of TDLS teardown packet from peer or internal timeout
configured during TDLS setup. Event is propogated to cfg80211
so that userspace application can take appropriate action.

83f7a85f11 iwlwifi: pcie: disable interrupts upon PCIe alloc
In case RFKILL is in KILL position, the NIC will issue an
interrupt straight away. This interrupt won't be sent
because it is masked in the hardware.
But if our interrupt service routine is called for another
reason (SHARED_IRQ), then we'll look at the interrupt cause
and service it. This can cause bad things if we are not
ready yet.
Explicitly clean the interrupt cause register to make sure
we won't service anything before we are ready to.

Also, handle correctly the CSA unbind-bind flow which is triggered by mac80211
