This is used only within PCIe, and there's no reason to go through
the transport methods for a function call within PCIe itself.
Remove the dump_regs() method and call the function directly.

A probe response built by a P2P GO should contain:
1. CSA/eCSA IE when relevant
2. If the corresponding probe request had P2P IE, then
need to add P2P IE with NOA attributes.
However, the NOA attributes and the updated channel switch
counter are known only to the FW. The solution is that FW
will send a notification with the relevant probe response
data and the driver will save it and update the probe
response accordingly.

A new FW API has been added for WOWLAN_GET_STATUSES to support
multiple GTK keys and IGTK keys. Check the respective TLV and use the
new API when it is set.
Let most of the code use the new version (v7) and convert the old
version (v6) to the new one when needed.
Also refactor some functions a bit so that they can be reused more
easily. Particularly the part that calls WOWLAN_GET_STATUSES which is
reused in D3 and D0i3.

The tid for Non-QOS frames is set to IWL_MAX_TID_COUNT. This value
is also used for configuring the queue for non-QOS data. However, this
tid is used by the FW for management queues. As a result, the FW
does not encrypt non-QOS data frames.
Fix this by setting the tid for non-QOS data frames to zero, which
is a valid value for data frames in the FW.
This also fixes a bug in sending multicast frames, where the queues
are allocated with tid == 0, but are sent with tid == 8, which may
lead to unexpected behavior.

Upon first calling read() on a debugfs file, invoke
iwl_dbgfs_##name##_read and store the response buffer on the heap, so
subsequent read() calls don't need to invoke said function again.
This is done because cat etc will call read() repeatedly until EOF is
reached (or read() returns 0), which in the current implementation will
cause said function to be invoked multiple times.
With the current implementation this can also cause buggy behavior in
some weird edge cases where the first invocation returns a string of
length n, and the second of length m>n: The last m-n characters of
the second invocation will be printed to screen.

Make wmm_rule be part of the reg_rule structure. This simplifies the
code a lot at the cost of having bigger memory usage. However in most
cases we have only few reg_rule's and when we do have many like in
iwlwifi we do not save memory as it allocates a separate wmm_rule for
each channel anyway.
This also fixes a bug reported in various places where somewhere the
pointers were corrupted and we ended up doing a null-dereference.

wireless-drivers-next patches for 4.19
This time a bigger pull request as we have two new Mediatek drivers
MT76x2u (CONFIG_MT76x2U) and MT76x0U (CONFIG_MT76x0U). Also iwlwifi got
support for the new IEEE 802.11ax standard, the successor for
802.11ac. And naturally smaller new features and bugfixes all over.
Major changes:
wcn36xx
* fix WEP in client mode
wil6210
* add support for Talyn-MB (Talyn ver 2.0) device
* add support for enhanced DMA firmware feature
iwlwifi
* implement 802.11ax D2.0
* support for the new 22560 device family
* new PCI IDs for 22000 and 22560
qtnfmac
* implement cfg80211 power management callback
* enable multiple SSIDs scan support
* qtnfmac: implement basic WoWLAN support
mt7601u
* fall back to software encryption for hw unsupported ciphers
* enable 802.11 Management Frame Protection (MFP)
mt76
* support setting RTS threshold
* add USB support
* add support for MT76x2u devices
* add support for MT76x0U devices
mwifiex
* allow user space to set all other IEs except WMM IE
rsi
* add firmware support for AP+BT dual mode

The periphery can't be accessed before we set the
INIT_DONE bit which initializes the device.
A previous patch added a reconfiguration of the MSI-X
tables upon resume, but at that point in the flow,
INIT_DONE wasn't set. Since the reconfiguration of the
MSI-X tables require periphery access, it failed.
The difference between WoWLAN and without WoWLAN is that
in WoWLAN, iwl_trans_pcie_d3_suspend clears the INIT_DONE
without clearing the STATUS_DEVICE_ENABLED bit in the
software status. Because of that, the resume code thinks
that the device is enabled, but the INIT_DONE bit has been
cleared.
To fix this, don't reconfigure the MSI-X tables in case
WoWLAN is enabled. It will be done in
iwl_trans_pcie_d3_resume anyway.

in which the vid is stored in the structs' rbid

used_bd, the used list, uses the iwl_rx_completion_desc

rb_stts, the hw "write" pointer of rx is stored in a

The iwl_rx_transfer_desc struct is part of the free list,

Nowadays, the tfd queue max size is 2^8, and the reserved size in the
command header sequence field for the tfd entry index is 8 bits,
allowing an injective function from the hw pointers to the tfd entry index
in the sequence field.
In 22560 devices the tfd queue max size is 2^16, meaning that
the hw pointers are 16 bit long (allowing to point to each entry
in the tfd queue). However, the reserved space in the sequence field for
the tfd entry doesn't change, and we are limited to 8 bit.
This requires cancelling the injective function from hw pointer to
tfd entry in the sequence number.
Use iwl_pcie_get_cmd_index to wrap the hw pointer's to the n_window
size, which is maximum 256 in tx queues, and so, keep the injective
function between the window wrapped hw pointers to tfd entry index in
the sequence.
