d954cd7700 ath9k: fix pending tx frames accounting
Packets originally buffered for the regular hardware tx queues can end
up being transmitted through the U-APSD queue (via PS-Poll or U-APSD).
When packets are dropped due to retransmit failures, the pending frames
counter is not always updated properly.
Fix this by keeping track of the queue that a frame was accounted for in
the ath_frame_info struct, and using that on completion to decide
whether the counter should be updated.
This fixes some spurious transmit queue hangs.

b48d891676 brcmfmac: rework wiphy structure setup
Instead of waiting for IFF_UP of the primary net device to determine
the band and channel information of the wiphy structure, this is now
done during driver initialization in brcmf_cfg80211_attach(). The
channel information is obtained from the device and the 2G band is
updated when 40MHz bandwidth is enabled for that band. Before this
change the band and channel objects were common between multiple
brcmfmac devices in the system, which make that information rather
unreliable. That is also fixed with this reworked implementation.

82d957e09d brcmfmac: rework debugfs functions in the driver
Reworked the debugfs functions in the driver making it easier for
other driver parts to add a debugfs entry and keeping the information
they want to expose in debugfs private, ie. not in a header.

This is accomplished by providing the function brcmf_debugfs_add_entry()
in which the caller provides a read function in which they provide the
content. The debugfs function will take care of creating the debugfs
entry and cleaning up upon removal.

d5343f0690 mwifiex: fix corner case system hang issue
Sometimes pending internal scan commands are delayed to give
preference to Tx traffic. 'scan_processing' flag has been
checked at the beginning of delay timer routine to know if in the
meantime scan operation has been cancelled.

There is a corner case where pending scan commands are emptied
after scan_processing flag check is passed. In this case
wrong pointer returned by list_first_entry() is passed to
list_del() which causes system hang.

This patch fixes the issue by adding list_empty() check.

Support for N-PHY rev 8 with 0x2057 rev 5 is almost ready, but we still

The tx ring index was immediately trimmed with a

a491a920ff ath10k: fix unregister deadlock when fw probe fails
If firmware probing worker failed it called
device_release_driver() which synchronously called
remove() pci callback. The callback in turn waited
for the worker that called it to finish resulting
in a deadlock.

Waiting for a completion instead of a worker, like
some other drivers do, doesn't seem like the best
idea either:

  Syscall                 Worker

                          probe_fw()
  rmmod
  dev_lock()
  pci->remove()
  wait_for_completion()
                          complete_all()
                          device_release_driver()
                          dev_lock()
                          [sleep]
  free(ar)
  dev_unlock()
                          [resume]

There's no guarantee that Worker upon resuming can
still access any data/code of the module.

Leaving device bound to a driver is not as harmful
as deadlocking so remove the call to
device_release_driver() while a proper solution is
figured out.

This patch change things in order to allocate that variable via

propagating the error.

This scenario may result in packet loss, since the transmission may start

potential packet loss disable tx to all the stations when the channel
switch flow starts. Clear the disable_tx bit when a station is seen on a
target channel, or after IWL_MVM_CS_UNBLOCK_TX_TIMEOUT beacons on a new

f0c9778396 iwlwifi: mvm: CSA unbind-bind flow support for client
Implement support for unbind-bind flow for the client roles.  This
includes telling the firmware that we are not associated, removing
time-events, removing quotas and updating power management during the
actual switch, and redoing everything in the new channel.

b08c1d972a iwlwifi: mvm: add switch_vif_chanctx operation
Implement the switch_vif_chanctx operation with support for a
single-vif and SWAP mode.  The REASSIGN mode and multi-vifs are not
supported yet.

This operation needs to implement 4 steps, namely unassign, remove,
add and assign the chanctx.  In order to do this, split out these
operations into locked and non-locked parts, thus allowing us to call
them while locked.

Additionally, in order to allow us to restart the hardware when
something fails, add a boolean to the iwl_mvm_nic_restart() function
that tells whether the restart was triggered by a FW error or
something else.

0166230c6c iwlwifi: mvm: remove update type argument from quota update
It turns out that adding the update type argument was pointless as
quota update is never called from the add_interface() callback.
Therefore, IWL_MVM_QUOTA_UPDATE_TYPE_NEW isn't actually needed and
then only a "disabled_vif" argument is needed for the upcoming CSA
work.

Remove the whole enum iwl_mvm_quota_update_type and pass the right
arguments (always NULL for disabled vif right now) to the function
in all current call sites.

63faceb60b iwlwifi: mvm: don't send zero quota to the firmware
There are some cases where we can currently send zero quota
for a valid binding, e.g. if we update while an interface is
bound to a channel context but not yet acting as an AP.

Avoid this by reordering the checks.

63cbe180f8 iwlwifi: mvm: let iwl_mvm_update_quotas disregard a disabled vif
In some cases (e.g. when we're doing a channel switch), we may need to
disable the quota of a vif temporarily.  In order to do so, add an
argument to the iwl_mvm_update_quotas() function to tell if the passed
vif is a new one or if it should be disregarded.

ae969afe43 iwlwifi: mvm: rs: don't clear persistent fields
iwl_mvm_rs_rate_init() is called multiple times to re-init
the rate scaling statistics (e.g. after some idle time).

It clears all the lq_sta sta, including some fields that
shouldn't be cleared (e.g. debugfs pointers). Fix it
by adding a new 'persistent' sub-struct, and
avoid clearing it on (re-)init.

Move the initialization of the persistent fields to
rs_alloc_sta instead.
