We should not allow diversity when BT Coex needs the second
antenna. Thermal Throttling can also request to stop using
the second antenna. Honour those requests.

In some situations (see comment) it makes sense to enable both
chains (if available) to get better throughput by having chain
diversity available.

CMD_SYNC is really 0 which is confusing:
if (cmd.flags & CMD_SYNC) is always false.
Fix this by simply removing its definition.

There's no need to use a variable just to return the result
of another function call at the end of a function, remove it.

These inlines are pretty pointless now as they just return a
fixed struct value, remove them - the code even gets shorter.

For testing the D3 (WoWLAN) firmware, it is useful to be able
to run the firmware with instrumentation while the host isn't
sleeping and can poke at the firmware debug logging etc.
Implement this by a debugfs file. When the file is opened the
D3 firmware is loaded and all regular commands are blocked.
While the file is being read, poll the firmware's PME status
flag and report EOF once it changes to non-zero. When it is
closed, do (most of) the resume processing. This lets a user
just "cat" the file. Pressing Ctrl-C to kill the cat process
will resume the firwmare as though the platform resumed for
non-wireless reason and when the firmware wants to wake up
reading from the file automatically completes.
Unlike in real suspend, only disable interrupts and don't
reset the TX/RX hardware while in the test mode. This is a
workaround for some interrupt problems that happen only when
the PCIe link isn't fully reset (presumably by changing the
PCI config space registers which the core PCI code does.)
Note that while regular operations are blocked from sending
commands to the firmware, they could still be made and cause
strange mac80211 issues. Therefore, while using this testing
feature you need to be careful to not try to disconnect, roam
or similar, and will see warnings for such attempts.
Als note that this requires an upcoming firmware change to
tell the driver the location of the PME status flag in SRAM.
D3 test will fail if the firmware doesn't report the pointer.

In some botched (!) restart scenarios we seem to get here with
a NULL PHY context, so warn and exit instead of crashing.

1. All the phy contexts are added immediately after the
firmware is loaded and up.
2. Whenever a PHY context needs to be used, its reference
counter is incremented and the PHY context is being
configured to the appropriate configuration.
3. When a PHY context is no longer needed, its reference
count is decremented.
4. PHY contexts are never removed.

In current implementation, the phy context is tightly coupled
with the channel context. This complicates the possibility of
using the same phy context for both netdev interfaces and the P2P
Device interface. To loosen this coupling:
1. Manage all the phy contexts in the mvm op mode, and only save
the phy context id in the chanctx memory.
2. Reference count the phy contexts and free them only when they
are not longer used (both by mac80211 and P2P Device).

Newer firmware revisions have a completely new
firmware API. This is the new driver for this
new API.
I've listed the people who directly contributed
code, but many others from various teams have
contributed in other ways.
