9ba85e9edf drop packets if a WME queue gets too long. 
similar code was removed in r3503, but it was wrong before as well, because
the packet needs to be dropped instead of requeued to actually achieve
prioritization between different packet types (WME classes). if we allow
one queue to consume all TX buffers then there is no buffer left to service
packets on higher priority queues.

c4093cb5c8 Manually stomp the DMA size to 128B for AR5418 devices. This patch should probably be extended to do this for all PCIe devices. 
The register defines were taken from ath5k.

This patch has been only lightly tested, I'm afraid - trying for more coverage.

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.

dfdda8ca55 Remove axq_link, for benoit. 
The last descriptor is now implicit in the structure and meta-data of the buffers; axq_link does not need to be maintained separately.
Add macros to to return the last buffer, descriptor, and link them as necessary.
Make the queue moving macro implicitly link descriptors, and remove the explicit descriptor linking in this case.

ath_node_move_data is still desperately in need of a review; it is used in XR.

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.
