NSS is a argument of highest rate in RC, and it occupies bit 4-7 so use
ieee80211_rate_set_vht() to fill the values. Since it got correct rate
index, we don't need to check chips to assign NSS in set function anymore.

In older design, the TX power is grouped into rate section (smaller array
size), but new design groups them into rate (larger array size). Thus,
we extend the size for both cases, and add compile time assertion.

In new design, SW_DEFINE[1:0] of tx desc are used by firmware, and the TX
report only contains SW_DEFINE[7:0]. To satisfy with all cases, driver uses
SW_DEFINE[7:2] as sequence number.
Besides, the format of tx report have been changed, so a new flag
RTL_SPEC_EXT_C2H is used to access report.

In case there is no valid MAC address kernel generates random one. This
patch propagate this generated MAC address back to NVS data which will be
uploaded to wl1251 chip. So HW would have same MAC address as linux kernel
uses.
This should not change any functionality, but it is better to tell wl1251
correct mac address since beginning of chip usage.

This patch implements parsing MAC address from NVS data which are sent to
wl1251 chip. Calibration NVS data could contain valid MAC address and it
will be used instead of randomly generated one.
This patch also moves code for requesting NVS data from userspace to driver
initialization code to make sure that NVS data will be there at time when
permanent MAC address is needed.
Calibration NVS data for wl1251 are device specific. Every device with
wl1251 chip should have been calibrated in factory and needs to provide own
calibration data.
Default example file wl1251-nvs.bin, found in linux-firmware repository,
contains MAC address 00:00:20:07:03:09. So this MAC address is marked as
invalid as it is not real device specific address, just example one.
Format of calibration NVS data can be found at:

Before this patch, driver generated random MAC address every time it was
initialized. After that random MAC address could be overwritten with fixed
one, if provided.
This patch changes order. First it tries to read fixed MAC address and if
it fails then driver generates random MAC address.

Whenever ath10k firmware discards a packet (HTT_TX_COMPL_STATE_DISCARD
flag), the skb is freed and mac80211 does not get feedback through
ieee80211_tx_status().
Instead, make sure that the IEEE80211_TX_STAT_ACK flag is disabled and
let the packet go through, like ath9k does.

We're obviously not part of a memory reclaim path, so don't set the flag.
This also causes a warning in check_flush_dependency() since we end up
in a code path that flushes a non-reclaim workqueue, and we shouldn't do
that if we were really part of reclaim.

In AP mode, when a new station associates, rs is initialized immediately
upon association completion, before the phy context is updated with the
association parameters, so the sta bandwidth might be wider than the phy
context allows.
To avoid this issue, always initialize rs with 20mhz bandwidth rate, and
after authorization, when the phy context is already up-to-date, re-init
rs with the correct bw.

Our Transmit Frame Descriptor (TFD) is a DMA descriptor that
includes several pointers to be able to transmit a packet
which is not physically contiguous.
Depending on the hardware being use, we can have 20 or 25
pointers in a single TFD. In both cases, it is more than
enough and it is quite hard to hit this limit.
It has been reported that when using specific applications
(Ktorrent), we can actually use all the pointers and then
a long standing bug showed up.
When we free the TFD, we check its number of valid pointers
and make sure it doesn't exceed the number of pointers the
hardware support.
This check had an off by one bug: it is perfectly valid to
free the 20 pointers if the TFD has 20 pointers.
Fix that.

In IBSS, the mac80211 sets the cab_queue to be invalid.
However, the multicast station uses it, so we need to override it.
A previous patch did it, but it was nested inside the if's and was
applied only for legacy FWs that don't support the new station type
API, instead of being applied for all paths.
In addition, add a missing NL80211_IFTYPE_ADHOC to the initialization
of the queues in iwl_mvm_mac_ctxt_init()

A previous patch allowed the same PN for packets originating from the
same AMSDU by copying PN only for the last packet in the series.
This however is bogus since we cannot assume the last frame will be
received on the same queue, and if it is received on a different ueue
we will end up not incrementing the PN and possibly let the next
packet to have the same PN and pass through.
Change the logic instead to driver explicitly indicate for the second
sub frame and on to be allowed to have the same PN as the first
subframe. Indicate it to mac80211 as well for the fallback queue.

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

There has been a coding error in rtl8821ae since it was first introduced,
namely that an 8-bit register was read using a 16-bit read in
_rtl8821ae_dbi_read(). This error was fixed with commit 40b368af4b75
("rtlwifi: Fix alignment issues"); however, this change led to
instability in the connection. To restore stability, this change
was reverted in commit b8b8b16352cd ("rtlwifi: rtl8821ae: Fix connection
lost problem").
Unfortunately, the unaligned access causes machine checks in ARM
architecture, and we were finally forced to find the actual cause of the
problem on x86 platforms. Following a suggestion from Pkshih
<pkshih@realtek.com>, it was found that increasing the ASPM L1
latency from 0 to 7 fixed the instability. This parameter was varied to
see if a smaller value would work; however, it appears that 7 is the
safest value. A new symbol is defined for this quantity, thus it can be
easily changed if necessary.

Add a NL_ERR_MSG in case of creating a radio by a netlink message to give
clear output to the creating process instead of creating only a debug
message in kernel log. The same function is used for the creation while
module load, so keep the old message, although it should never be thrown
while load, because the module controls all mac addresses.

If simulation needs predictable permanent mac addresses of hwsim wireless
phy, this patch add the ability to create a new radio with a user defined
permanent mac address. Allowed mac addresses needs to be locally
administrated mac addresses (as also the former fixed 42:* and 02:* were).
To do not break the operation with legacy software using hwsim, the new
address is set twice. The problem here is, the netlink call backs use
wiphy->addresses[1] as identification of a radio and not the proposed
permanent address (wiphy->addresses[0]). This design decision is not
documented in the kernel repo, therefore this patch simply reproduces this,
but with the same address.

Pull poll annotations from Al Viro:
"This introduces a __bitwise type for POLL### bitmap, and propagates
the annotations through the tree. Most of that stuff is as simple as
'make ->poll() instances return __poll_t and do the same to local
variables used to hold the future return value'.
Some of the obvious brainos found in process are fixed (e.g. POLLIN
misspelled as POLL_IN). At that point the amount of sparse warnings is
low and most of them are for genuine bugs - e.g. ->poll() instance
deciding to return -EINVAL instead of a bitmap. I hadn't touched those
in this series - it's large enough as it is.
Another problem it has caught was eventpoll() ABI mess; select.c and
eventpoll.c assumed that corresponding POLL### and EPOLL### were
equal. That's true for some, but not all of them - EPOLL### are
arch-independent, but POLL### are not.
The last commit in this series separates userland POLL### values from
the (now arch-independent) kernel-side ones, converting between them
in the few places where they are copied to/from userland. AFAICS, this
is the least disruptive fix preserving poll(2) ABI and making epoll()
work on all architectures.
As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
it will trigger only on what would've triggered EPOLLWRBAND on other
architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
at all on sparc. With this patch they should work consistently on all
architectures"

Apparently hardware does not perform CCMP PN validation in hardware, so
we need to take care of this in the driver. This is important for
protecting against replay attacks.
Since validation of fragmented frames is more complex, the CCMP header
for those is preserved. To keep the counter in sync, the first fragment
is verified by both mt76 and mac80211, and all other fragments only by
mac80211.
