If an interface type changes from a type that is
only supported on the PAN context (e.g. P2P GO)
to a type that is supported on the BSS context,
and the BSS context is not in use, then we need
to use the BSS context instead of changing the
device type within the context. To achieve this,
refuse the type change, which causes a down/up
cycle that will allocate the BSS context for the
interface.

The current RXON checking doesn't verify that
the channel is valid (or at least non-zero),
so add that. Also, add a WARN() so we get a
stacktrace, and capture a bitmask of errors
in order to capture all necessary information
in the warning itself (in case the previous
messages are snipped off.)

There are a few cases like the WoWLAN support
I'm writing that require attempting to access
the NIC when it is known that it might not be
accessible, e.g. after the system woke up and
the platform might have reset the device.
To avoid messages in this case, introduce the
new function iwl_grab_nic_access_silent(), it
will only return an error status.

If a device error happens while the uCode is
being loaded or initialised, we will attempt
to restart the device (which will likely fail
again, but that's not the issue here). During
this new restart, we turn off the device, but
as the uCode failed to initialise it already
is turned off. As a consequence, grabbing NIC
access will fail and cause excessive messages
and hangs.
To fix this issue, introduce a new status bit
and only attempt to reprogram the device when
it isn't already disabled.

iwlwifi: do not set tx power when channel is changing
we set device tx power during initialization to priv->tx_power_next,
which itself is initialized to minimum power. That changed
default behaviour of driver. Previously we initialized device to
transmit at maximum available power by default. Patch change again
to previous behaviour and cleanup tx power initialization.
Fortunately this is not critical fix, as mac80211 layer setup
tx power lately to 14dB, hence device does not operate at minimal
transmit power all the time.

"iwlwifi: fix enqueue hcmd race conditions" move hcmd callback after
command queue reclaim, to avoid call it with hcmd_lock. But since
queue read index was updated, cmd data can be overwritten. Fix problem
by calling callback before taking hcmd_lock and queue reclaim.

The current firmware loading mechanism in
iwlwifi is very hard to follow, and thus
hard to maintain. To make it easier, make
the firmware loading synchronous.
For now, as a side effect, this removes a
number of retry possibilities we had. It
isn't typical for this to fail, but if it
does happen we restart from scratch which
this also makes easier to do should it be
necessary.

There's no point in running through iwl_down()
when we never registered with mac80211, as it
just cleans up internal structures that were
never initialised in this case. Therefore we
can also remove the special handling for this
case from __iwl_down().

The current code to read the error table header
just hardcodes all the offsets, which is a bit
hard to understand. We can read in the entire
header (as much as we need) into a structure,
and then take the data from there, which makes
it easier to understand. To read a bigger blob
we also don't need to grab NIC access for each
word read, making the code more efficient.

When testing some new P2P code, Angie found that the
driver might crash because the beacon command ended
up being bigger than a regular command. This is quite
obvious -- a normal command is limited to roughly 360
bytes but a beacon may be much larger of course.
To fix this, use the huge command buffer.

Since huge commands all share a single buffer,
there can only be a single one in flight at a
time since otherwise they'd overwrite each
other. This is true in the driver now, but it
seems like a possible source of bugs, so add

sent synchronously.
