This reverts commit bcc920e8f0.
Drivers gets hardware info and updates ht_cap field of
wiphy->bands during initialization. Once updated during init,
ht_cap must not be modified as it reflects the capability
supported by hardwawre. Above patch tries to modify the ht_cap
field and this results in wrongly advertising capabilities during
association.

the efficiency, RX skb queue is introduced.
Here, while preparing RX URB skb is allocated and used
for RX buffer. When rx done handler is called, enqueue the skb

Coex module just schedule the packets to firmware by taking them
from the corresponding paths.

this purpose. Protocol operations structure is global structure

The firmware has a requirement that the P2P_DEVICE address should
be different from the address of the primary interface. When not
specified by user-space, the driver generates the MAC address for
the P2P_DEVICE interface using the MAC address of the primary
interface and setting the locally administered bit. However, the MAC
address of the primary interface may already have that bit set causing
the creation of the P2P_DEVICE interface to fail with -EBUSY. Fix this
by using a random address instead to determine the P2P_DEVICE address.

hwsim_netgroup counter is declarated as int, and it is incremented
every time a new net is created. After sizeof(int) net are created,
it will overflow, and different net namespaces will have the same
identifier. This patch fixes the problem by introducing IDA instead
of int counter. IDA guarantees, all the net namespaces have the uniq
identifier.
Note, that after we do ida_simple_remove() in hwsim_exit_net(),
and we destroy the ID, later there may be executed destroy_radio()
from the workqueue. But destroy_radio() does not use the ID, so it's OK.
Out of bounds of this patch, just as a report to wireless subsystem
maintainer, destroy_radio() increaments hwsim_radios_generation
without hwsim_radio_lock, so this may need one more patch to fix.

In the scheduler config command, the meaning of tid == 0xf was intended
to indicate the configuration is for management frames. However,
tid == 0xf was also used for the multicast queue that was meant only
for multicast data frames, which resulted with the FW not encrypting
multicast data frames.
As multicast frames do not have a QoS header, fix this by setting
tid == 0, to indicate that this is a data queue and not management
one.

When the GTK is installed, we install it to HW with the
station ID of the AP.
Mac80211 will try to remove it only after the AP sta is
removed, which will result in a failure to remove key
since we do not have any station for it.
This is a valid situation, but a previous commit removed
the early return and added a return with error value, which
resulted in an error message that is confusing to users.

Trying to collect firmware debug data while firmware

This causes even a bigger issue if at that time the

In that case, when later turning the radio on, the Driver
fails to read the HW (registers contain garbage values).
(It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN

We should add the multicast station before adding the

However, in older FW, the firmware will start beaconing
when we add the multicast station, and since the broadcast
station is not added at this point so the transmission

deleted (mainly from del_virtual_intf operation).
Instead of adding another mutex, use p2p_wdev_mutex and rename
it to vif_mutex to reflect the added role. Its existing roles
are similar so it extends nicely (for example it protects the
scan_request member which is also a member of wil6210_vif).

Add generic support in cfg80211 operations add_virtual_intf
and del_virtual_intf for adding/removing VIFs of any
interface type, and fix change_virtual_intf to allow changing
the interface type of a VIF. Previously these operations
only worked for the P2P_DEVICE interface which is not a real
VIF(it is management-only and shares radio with the main
interface).
Currently the interface combination is validated, the VIF is
added/removed in the firmware and the appropriate net/wireless
device is also added/removed.
Added minimal support for proper interface up/down and module
unload but most operations still work only on the main interface.

Simple infrastructure changes for supporting multiple
virtual interfaces (multiple VIFs).
It is still not possible to add new VIFs so the only VIF
belongs to the main interface.
Main changes:
1. Add MAC ID(mid) argument to wmi_send and wmi_call to
allow invoking WMI commands on different VIFs.
2. Similarly, in WMI event handler look at the mid reported
by FW and extract VIF structure (currently only for main
interface). All WMI event handlers operate on wil6210_vif
structure so they know on which VIF they were called.
3. Trivial changes to use wil6210_vif structure and MID
throughout the code.
4. Various changes to logging to report MID.
More complete multiple VIFs support will be added gradually
in next patches.

For supporting multiple virtual interfaces in the future,
introduce a wil6210_vif structure which will hold per-VIF
data. Change the module initialization so wil6210_vif will
be part of net_device structure, and wireless_dev will be
embedded inside the wil6210_vif structure. This will allow
us to find the appropriate wil6210_vif structure when we

permanent MAC address is needed.
Calibration NVS data for wl1251 are device specific. Every device with

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.

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.

Canceling the periodic timestamp work should be
done in the opposite flow to where it was started.
This also prevents from sending the MARKER command
during the mac_stop flow - causing a false queue hang
(FW is no longer there to send a response).

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.
