There is a macro for converting TX response rate to a
rate scale value, use it.

39f1332c52 rsi: move rsi_sdio_reinit_device() out of CONFIG_PM
This function is generic. It doesn't contain wowlan specific code.

db5c6d4a9b qtnfmac: advertise support of inactivity timeout
Wireless device may implement a logic to kick-out STA due to inactivity
for a certain period of time. This feature needs to be advertised to
higher layers if supported. Timeout value is still taken from

c35c0d54a7 qtnfmac: modify full Tx queue recovery
Current recovery approach is to wake s/w Tx queues for skb->dev netdevice.
However this approach doesn't cover the case when h/w queue is full of
packets from a single wireless interface. Suppose xmit attempt from the
second wireless interface fails due to failed reclaim. Then the second
interface will not have a chance to recover even if subsequent reclaims
succeed. Possible solution is to attempt to wake all the s/w queues
belonging to driver interfaces.

063848c3e1 rsi: sdio: Add WOWLAN support for S5 shutdown state
Unlike other power states, WoWLAN configuration does not come from
mac80211 for shutdown. Hence configuring the WoWLAN from shut down
callback it self. Remaining steps of disabling SDIO interrupts,
setting 'MMC_PM_KEEP_POWER' flag are same as other power states.

698dbbf82b wil6210: remove SSID debugfs
This driver shouldn't be using wdev->ssid to start with, as
it's more or less an internal field in cfg80211 used for
various purposes. Reading it is possible through nl80211,
even if that's not really what we should be doing there
for anything but AP type interfaces.

It *really* shouldn't allow modifying it!

The Current firmware 10.4-3.5.1-00035 on QCA9888 does not

either driver needs to block the offchannel operation requests

20665a9076 ath10k: fix build errors with !CONFIG_PM
Build errors have been reported with CONFIG_PM=n:

drivers/net/wireless/ath/ath10k/pci.c:3416:8: error: implicit
declaration of function 'ath10k_pci_suspend'
[-Werror=implicit-function-declaration]

drivers/net/wireless/ath/ath10k/pci.c:3428:8: error: implicit
declaration of function 'ath10k_pci_resume'
[-Werror=implicit-function-declaration]

These are caused by the combination of the following two commits:

6af1de2e4e ("ath10k: mark PM functions as __maybe_unused")
96378bd2c6 ("ath10k: fix core PCI suspend when WoWLAN is supported but
disabled")

Both build fine on their own.

But now that ath10k_pci_pm_{suspend,resume}() is compiled
unconditionally, we should also compile ath10k_pci_{suspend,resume}()
unconditionally.

And drop the #ifdef around ath10k_pci_hif_{suspend,resume}() too; they
are trivial (empty), so we're not saving much space by compiling them
out. And the alternatives would be to sprinkle more __maybe_unused, or
spread the #ifdef's further.

Build tested with the following combinations:
CONFIG_PM=y && CONFIG_PM_SLEEP=y
CONFIG_PM=y && CONFIG_PM_SLEEP=n
CONFIG_PM=n

0425f07959 brcmsmac: split up wlc_phy_workarounds_nphy
The stack consumption in this driver is still relatively high, with one
remaining warning if the warning level is lowered to 1536 bytes:

drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_n.c:17135:1: error: the frame size of 1880 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]

The affected function is actually a collection of three separate implementations,
and each of them is fairly large by itself. Splitting them up is done easily
and improves readability at the same time.

I'm leaving the original indentation to make the review easier.

Kalle Valo says:

====================
wireless-drivers-next patches for 4.15

The first pull request for 4.15, unusually late this time but still
relatively small. Also includes merge from wireless-drivers to fix
conflicts in iwlwifi.

Major changes:

rsi

* add P2P mode support

* sdio suspend and resume support

iwlwifi

* A fix and an addition for PCI devices for the A000 family

* Dump PCI registers when an error occurs, to make it easier to debug

rtlwifi

* add support for 64 bit DMA, enabled with a module parameter

* add module parameter to enable ASPM
====================

d3e99b2d19 net/cw1200: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

This variable is never used, so remove the code to set it.
After this, the variable 'iph' also has the same fate.

1105a33737 iwlwifi: pcie: sort IDs for the 9000 series for easier comparisons
It's hard to find values that are missing in the list, so sorting the
values and comparing them makes it much easier.  To simplify this
task, sort the devices in the list.

41fd2fec56 iwlwifi: mvm: add missing lq_color
In the compressed BA notif, the driver didn't parse out
the LQ color, so statistics for the rates tried were
always thrown out. Add it so it gets correctly used.

While at it, fix the name of the relevant field in the
struct.

3485e76e73 iwlwifi: define minimum valid address for umac_error_event_table in cfg
We now have two different minimum valid values for
umac_error_event_table.  To avoid hardcoding the minimum value in the
driver, add a value to cfg where it can be read from.

fb5b28469d iwlwifi: mvm: move umac_error_event_table validity check to where it's set
There's no point in checking the validity of the
umac_error_event_table pointer every time we generate a dump.  It's
cleaner to do so when we read the value, namely when we receive the
alive data.

All callers of iwl_mvm_release_frames() already have the baid_data
pointer, so we don't need to (re)calculate it inside the function.
Just pass it instead.

3f1c4c5806 iwlwifi: mvm: remove duplicated fields in mvm reorder buffer
The reason station id and tid fields are both in baid data and
in the reorder buffer per queue is that we couldn't access the
baid_data in the reorder timer functions.
Now that we do some pointer math and access it anyway, those
fields can be removed.
This save some space and some code.

dfdddd92a5 iwlwifi: mvm: allocate reorder buffer according to need
Now that we may have up to 256 entries per reorder buffer, and possibly up
to 16 queues, we can use a LOT of memory for this (64k for each station).
Allocate it according to what we need, which is of course much less for HT
stations (only 16k at a max of 16 queues).

However, this comes at the expense of complicating the code a bit to
calculate the right entry structure to use for each frame.
