John W. Linville says:

====================
This is another batch of fixes intended for the 3.11 stream.  FWIW,
this is the first request with fixes from the mac80211 and iwlwifi
trees as well.

Regarding the mac80211 bits, Johannes says:

"Here I have a fix for RSSI thresholds in mesh, two minstrel fixes from
Felix, an nl80211 fix from Michal and four various fixes I did myself."

As for the iwlwifi bits, Johannes says:

"Here I have a fix for debugfs directory creation (causing a spurious
error message), two scanning fixes from David Spinadel, an LED fix and
two patches related to a BA session problem that eventually caused
firmware crashes from Emmanuel and a small BT fix for older devices as
well as a workaround for a firmware problem with APs with very small
beacon intervals from myself."

Along with those:

Arend van Spriel addresses a lock-up and a NULL pointer dereference
in brcmfmac.

Daniel Drake fixes an unhandled interrupt during device tear down
in mwifiex.

Larry Finger corrects a wil6210 build error.

Oleksij Rempel fixes two ath9k_htc problems related to keeping the
driver and firmware in sync.

Solomon Peachy gives us a cw1200 fix to avoid an oops in monitor mode.

build_skb() specifies that the data parameter must come from a kmalloc'd
area, this is only true if frag_size equals 0, because then build_skb()
will use kzsize(data) to figure out the actual data size. Update the
comment to reflect that special condition.

The work queue is initialised in rtl_open (when the interface goes up),
but canceled in rtl_remove_one (when the PCI device gets removed). If
the network interface is not brought up, then the work queue struct is
not initialised. When the device is removed, the attempt to cancel the
uninitialised work queue causes a lockdep warning.

This patch fixes the issue by moving cancel_work_sync to rtl_close (to
match rtl_open). (Note that rtl_close is also called via
unregister_netdev in rtl_remove_one.)

There is no software way to reset adpter.

This patch add initial configuration and set it in

During tear down (e.g. mwifiex_sdio_remove during system suspend),
mwifiex left IRQs enabled for a significant period of time when it was
unable to handle them correctly. This caused interrupt storms and
interfered with the bluetooth interface on the same SDIO card.

Solve this by disabling interrupts at the point when they can no longer
be handled correctly, which is at the start of mwifiex_remove_card().

For cleanliness, we now enable interrupts in the mwifiex_add_card() path,
to be symmetrical with the disabling of interrupts. We also couple the
registration of the sdio IRQ handler with the actual enable/disable of
interrupts at the hardware level.

I also removed a write to this register in mwifiex_init_sdio which seemed
pointless and won't cause any ill effects now that we only register
the SDIO IRQ handler when we are ready to accept interrupts.

Includes some corrections from Amitkumar Karwar.

NAPI poll function does not re-enable the interrupt, if __QLCNIC_DEV_UP is not set
in adapter state. This was preventing driver from receiving any packet.

There are two race conditions in existing code for doing IGMP
management in workqueue in vxlan. First, the vxlan_group_used
function checks the list of vxlan's without any protection, and
it is possible for open followed by close to occur before the
igmp work queue runs.

To solve these move the check into vxlan_open/stop so it is
protected by RTNL. And split into two work structures so that
there is no racy reference to underlying device state.
