The time event is initialized relatively late in interface (mvmvif)
initialization, so it's possible to fail before that happens. As a
consequence, the driver will crash if it ever tries to delete this
time event in case initialization was unsuccessful.
Avoid this by using the time event's vif pointer to indicate validity.
The vif pointer is != NULL whenever the id is != TE_MAX, except for
this special error case where the vif pointer will have the correct
property (as the whole memory is cleared on allocation) whereas the
id is 0, causing a crash in trying to delete the time event from the
list.

When BT is active, we want to avoid the shared antenna for
management frame to make sure we don't disturb BT. There
was a bug in that code because it chose the antenna
BIT(ANT_A) where ANT_A is already a bitmap (0x1). This
means that the antenna chosen in the end was ANT_B.
While this is not optimal on devices with 2 antennas (it'd
disturb BT), it is critical on single antenna devices like
3160 which couldn't connect at all when BT was active.

In scenarios where we haven't converged yet to a specific modulation

This avoids being presented with low legacy rates when rs just begins

In practice there's no point in having a copy of

Most of the time the channel pointer (and band

after a chanctx is created because switching is
done using explicit chanctx swapping via
switch_vif_chanctx().
The only thing that can change within a
chanctx_conf and is used by the driver is
radar_enabled and channel width. These are however
always accessed in adequate mac80211 callback

Recently Broadcom added support for NVRAMs with entries for multiple
PCIe devices. One of the supported formats is based on prefixes defined
like: devpath0=pcie/1/4/ and entries like 0:foo=bar 0:baz=qux etc.
Unfortunately there are also a bit older devices using different way of
defining prefixes, e.g. SmartRG SR400ac (2 x BCM43602) with entries:
devpath0=pci/1/1/
devpath1=pci/2/1
Broadcom stated this old format will never be used/supported by brcmfmac
but given the simplicity of this patch I'll insist on supporting it.

After the new ciphers CCMP-256 and GCMP-128/256 were implemented,
wpa_supplicant could start negotiating them and use the software
implementation. This, however, breaks D3 behaviour in the driver
since it means that WoWLAN will not be possible.
To avoid breaking that feature, advertise only ciphers that the
hardware supports.

Currently, loading the firmware fails when it has higher API or CAPA
bits than the driver supports. That's an issue with integration.
At the same time, actually using api[0] and capa[0] will become
confusing when we also have api[1] and capa[1], and it's almost
certain that we'll mix up the bits and use the bits for api[1] with
api[0] by accident.
Avoid all this by translating the API/CAPA bits to the regular kernel
test_bit() format, and also providing wrapper functions. Also use the
__bitwise__ facility of sparse to check that we're testing the right
one.

As a preperation for multiple RX queues change the RBD
allocation model.
The new model includes a background allocator. The allocator is
called by the interrupt handler when there are two released
buffers by the queue, and the allocator starts allocating eight
pages per request.
When the queue has released 8 pages it tries claiming the
request. If the pages are not ready - it keeps claiming.
This new model should make sure that RBDs are always available
across the multiple queues.
The RBDs are transferred between the allocator and the queue.
The queue moves the free RBDs upon freeing them to the allocator.
The allocator moves them back to the queue's possession when the
request is claimed.
The allocator has an initial pool to make sure there are always RBDs
available for the request completion.
Release of the buffers at exit is done per pools - the allocator
frees its own initial pool and the queue frees its own pool.
Existing code refactor -
-Queue's initial pool is the size of the queue only as the allocation
of the new buffers no longer uses this pool.
-Removal of replenish background work, and replenish calls in the
interrupt handler and restock().
-The replenish() and the rxq used_list are used only during
initialization.
-Moved page allocation to a new function for code reuse.
New code -
Allocator code - new structure and functions.
Interrupt handler uses the allocator functions for replenishing buffers.
Reuse of the restock() method.
