The current mwl8k_priv->fw_lock spinlock doesn't actually protect
against multiple commands being submitted at once, as it is not kept
held over the entire firmware command submission. And since waiting
for command completion sleeps, we can't use a spinlock anyway.
To fix mwl8k firmware command serialisation properly, we have the
following requirements:
- Some commands require that the packet transmit path is idle when
the command is issued. (For simplicity, we'll just quiesce the
transmit path for every command.)
- There are certain sequences of commands that need to be issued to
the hardware sequentially, with no other intervening commands.
This leads to an implementation of a "firmware lock" as a mutex that
can be taken recursively, and which is taken by both the low-level
command submission function (mwl8k_post_cmd) as well as any users of
that function that require issuing of an atomic sequence of commands,
and quiesces the transmit path whenever it's taken.

Delete most of the mwl8k_work_struct fields and options, since most
of them are unused or never changed from their defaults:
- We always use priv->config_wq, so delete the wqueue argument from
mwl8k_queue_work().
- MWL8K_WQ_SPIN and MWL8K_WQ_POST_REQUEST are never used, as all
callers sleep for request completion, so sleep unconditionally.
- MWL8K_WQ_FREE_WORKSTRUCT is never used.
- MWL8K_WQ_TX_WAIT_EMPTY is always set, so assume it unconditionally.
- timeout_ms/txwait_attempts/tx_timeout_ms are never changed from
their defaults, so just hardcode these in the workqueue worker.
- step is never used.

Various mwl8k_txq_xmit changes:
- Extract the QoS field before adding the DMA header.
- Only write to tx->status once, and only after all the other
descriptor fields have been set.
- Do all tx state manipulation under the tx spinlock.
- Remove the priv->inconfig check, as all transmit queues will
be frozen during config cycles, so we won't ever be asked to
transmit if a config cycle is running.
- Remove some more dead code.

Since firmware load commands don't generate 'command done' interrupts
like normal commands do, polling for command done interrupts just
unnecessarily slows down the firmware load process. Removing this bit
of code speeds up loading a typical firmware image from 840 msec to
180 msec.

Adding and removing the DMA header that the mwl8k hardware requires
on tx and provides on rx can never fail, since we are guaranteed to
have enough headroom on the tx path to expand the packet, and we only
ever shrink the packet on the rx path. (And on both paths we are
guaranteed to be the only user of the skb we are handling.)
This allows removing all of the skb clone handling in the tx and tx
reclaim paths, and eliminates error checks in both the tx and rx
paths, simplifying the code a bit more.

mwl8k_configure_filter() passes pointers to total_flags and the
multicast address list to a workqueue function, while there is no
guarantee that those pointers will still be valid by the time the
workqueue function runs.
Solve this by passing total_flags by value, and by passing an
already built multicast address setup command packet to the workqueue
function so that we don't have to look at the multicast address list
itself outside of mwl8k_configure_filter().
Also, since ->configure_filter() can sleep now, wait synchronously
for the worker to finish.

Currently the beacon rssi that LPF gives is divided and rounded
up by ATH_RSSI_EP_MULTIPLIER twice. This will leave the incorrect rssi
in ANI. Having correct rssi in ANI fixes the connection stability at
< 30dB rssi range. This patch removes the unncessary computation of average
rssi over already valid average rssi. Also removes the redundant macros to
find average rssi.

My patch "cfg80211: fix deadlock" broke the code it
was supposed to fix, the scan request checking. But
it's not trivial to put it back the way it was, since
the original patch had a deadlock.
Now do it in a completely new way: queue the check
off to a work struct, where we can freely lock. But
that has some more complications, like needing to
wait for it to be done before the wiphy/rdev can be
destroyed, so some code is required to handle that.

In ath9k_stop(), tx_complete_work was being cancelled twice.
This patch fixes it. Also, locking sc->mutex should be done
at the beginning.

After initial power-up, the embedded cpu is usually halted. However,
if we down the interface and only do a soft reset before bringing
the interface back up, it will still be running and the firmware
loading code will bail out. This change halts the CPU before loading
the firmware, enabling a second call to wl1251_boot() to succeed
without a hard reset.

Mesh uses the tx failure average to compute the (m)path metric. This used to
be done inside the rate control module. This patch breaks the dependency
between the mesh stack and the rate control algorithm. Mesh will now work
independently of the chosen rate control algorithm.
The mesh stack keeps a moving average of the average transmission losses for
each mesh peer station. If the fail average exceeds a certain threshold, the
peer link is marked as broken.

rt2800pci can handle different retry rates,
it will always step 1 rate down after a failed
transmission so creating the retry rate list
for mac80211 is quite simple.

According to the original Ralink driver,
LG_FBK_CFG0_OFDMMCS2FBK should be initialized to 9 rather then 3.

In the TX descriptor the Packet ID must not be 0,
so add 1 to the ID. The wireless CLI ID is not allowed
to be 0 either, but also must be initialized with the
wcid value rather then keyid.

When the RX descriptor indicates the frame was L2 padded,
the SKBDESC_L2_PADDED flag should be set to make sure the
L2 padding is removed before it is send to mac80211.

Add new defines for RF chipsets which can be found
by the driver. We don't have to check for these
chips specifically yet, but it is better to have
the defines in now.
