a192279dd6 Only deliver frames to VAPs that are running.
This includes the reinstatement of the ieee80211_input_all function as this functionality should live in the net80211 layer. Unfortunately the code for this is a tad on the ugly side.

Thanks to OpenWRT/nbd: https://dev.openwrt.org/log/trunk/package/madwifi/patches/334-input.patch

Follow the rule of coding for the latest API.  Use __skb_queue_after()

Linux 2.6.26.  Provide compatibility definitions for __skb_queue_after()

9538bc8243 Remove the skb_copy call from ieee80211_input. However, create a copied SKB for each call to ieee80211_input when we are sending to all VAPs. Effectively, this means that we are using the SKB from the ath_buf except when ieee80211_input is called multiple times.

1b318d3853 Tidy RX queue processing code:
* Formatting
 * Add a function to remove SKB from ath_buf.
 * Call aforementioned function early if we are accepting a frame, so that there's not chance the data can get stomped on by DMA. We should probably do this for ignored frames as well, but I got fed up trying to sort out the stack of goto.
 * Remove some KASSERT for skb users, as the SKB are always copied.

7c6997619e This commit fixes problems with skbuff cloning and reference counting in input handling. The biggest problem with this code was corruption of memory.
ieee80211_input can receive cloned skb from the bridge layer, and thus makes copies to modify and use.  The original was being freed immediately upon copying.  The problem is that when you issue ANY response other than NETDEV_TX_OK the skb is returned to the kernel queue.  So, basically there were wild pointers to skb in the skb queue, and these skb were being re-used by other applications and drivers - resulting in crashes all over the place.

With this new logic, we keep the original around until we know whether or not we will requeue it NETDEV_TX_BUSY or consume it NETDEV_TX_OK and we correctly free the skb only when appropriate.

We also get rid of the net80211_input_all function which was doing a bunch of unnecessary (and broken) copies and noe updates.

017c006628 Improved debug tracing and support for cleaning up stalled CABQ.
When CABQ transfer finishes, HAL reports the queue as inactive.  Thus, if
we switch modes or change state the CABQ can be left with some ath_buf 
referenced by it.  The changes in this patch cause the CABQ to be checked
at DTIM even when no multicast is pending for the VAP and if "stalled"
then the queue is drained.  

A subsequent patch will fix the tx tasklet logic for CABQ.

80c58504d7 This patch cleans up the VAP creation API.
The need to use software instead of hardware for beacon timers in AP+STA mode (aka nosbeacon) is now just determined in software, as we always knew whether or not to enable this.

The confusing bssid and -bssid parameters are now deprecated.

The "uniquebssid" flag is equivalent to "bssid" and can be used to force IEEE80211_CLONE_BSSID flag.  If this is not specified, then the BSSID used will be the next unused BSSID in the sequence, which could very well be the parent device's MAC address.

"uniquebssid" equates directly to IEEE80211_CLONE_BSSID" flag therefore.

e906bf12da CCMP/AES Crypto module
So, ccmp_attach is called for each new key. Hence, only try to allocate a software context if IEEE80211_KEY_SWCRYPT is specified. Also, if we need a software context and fail, fail immediately; thus, the check in ccmp_setkey can be eleminated, as it is not actually a separate condition.

I think that when I touched this last, I was confused about the purpose of ccmp_attach.

4d5de4b5a2 This patch adds iwpriv values for setting the
time in ms, or the number of beacons for the
beacon miss alarm.  If we haven't had a beacon
in this period, the alarm is sounded and 
action (i.e. roaming) is taken.

This patch changes the storage of the beacon
miss threshold to integral beacon count but 
corrects the previous intent.

The default beacon miss alarm is going to be
850ms which is half way between the two hard
coded limits that were there before.

The old hard coded limits assumed that the
beacon interval was 100ms and set the limit to
10 (1000ms) for software beacon miss timer 
and 7 for hardware beacon miss timer.

The new default is 850ms (the midpoint between
the two previous defaults).  This value is rounded
up to the next nearest beacon interval.

There is no upper bound on the beacon miss
threshold specified, since it may need to be
wildly inflated with 25ms beacon interval, or
wildly reduced with 1000ms beacon interval.

The minimum is still 2 beacons, regardless of
the beacon interval.
