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. Signed-off-by:

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. Signed-off-by:

There is no need to check for NL80211_IFTYPE_MONITOR in ->add_interface(), as this function is never called for monitor interfaces. Also, there is no need to advertise this bit in our wiphy's ->interface_modes. Signed-off-by:

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. Signed-off-by:

Instead of passing a flag bitmask to mwl8k_cmd_802_11_radio_control, pass the 'enable' and 'force' arguments as separate parameters, and introduce wrappers for the common cases of enabling and disabling without forcing. Signed-off-by:

Other than ns_avgbrssi (Average beacon rssi) no data of ath9k_node_stats is being used anywhere. Nuke this structure and move its only useful member to ar5416Anistate. Also cleanup this redundant data in ath_softc. Signed-off-by:

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. Signed-off-by:

"cfg80211: fix alignment problem in scan request" introduced a bug into the error path, because now we allocate the entire scan request and not just the channel list (the channel list is allocated together with the scan request) -- on errors we thus also need to free the entire scan request.

Larry has started re-checking all current routines against a new version of the Broadcom MIPS driver. This patch implements the first round of changes he documented on the specs wiki. Also remove a few FIXMEs regarding missing initial values for variables with dynamic initial values where reading the values has been implemented. Signed-off-by:
