7559e86881 Add support for variable number of VAPs. The hard coded maximum of 4 VAPs is replaced by a module parameter so that you can specify from 2 to 64 VAPs. The only quirk with high numbers of VAPs is that you must not attempt to use staggered beacons because the hardware cannot fire them fast enough. If more than 4 VAP maximum is specified, beacons are always bursted. This code has been tested successfully against 16-VAP APs without problems.

4183b417a2 This is another case where we are getting clones of SKB and then modifying the header or the data. In a bridge, this is bad behavior. This fixes more bridge anomalies where incorrect header/data are sent to wired ports when packets are previously forwarded over madwifi port(s).

fa8be6633f Fromatting cleanup for r3152. To deal with a maximal 80C line length some clearly very silly things have had to be done; I think this is proabbly a goo dindication that code needs to be refactored or split out into seperate functions.

132f01bad9 Fix for bridging. We modify the packet's contents. Linux bridging code assumes it can clone the packet and send it to multiple interfaces without having it changed out from under it. Therefore, we need to clone each skb prior to modifying the copy. This fixes some very nasty bugs with bridged VAPs (esp with multiple VAPs in a bridge and multicast/broadcast traffic). 
The symptom would be fragments of 802.11 header showing up in the ethernet header because of skb header offsets being corrupted by MadWifi devices on lower ports which then get forwarded as-is to wired ports.

Sorry for the lame explanation, but the short end of the story is that you have to copy the skb before you modify it if you are going to play nice with bridging.

e6a0fd9b49 This patch refactors the layer 2 update frame sending logic into two routines. Both RNR and XID frames are sent to update bridges. The RNR is probably not the best way to update L2 bridges. It's basically telling the bridges and switches that the MAC is not able to receive traffic (i.e. congested or down) and we never send any other L2 packets to counteract any side effects of this. I also found that it didn't seem to be updating every MAC table on every bridge. XID, however, is the correct way, according to my research and we send XID to inform the bridges of the new location of the MAC as dictated by the standards. I left the RNR in there for good measure, since it doesn't appear to have any ill effects for anyone. (Hostapd ALSO sends XID when you are using hostapd... the redundancy is harmless and allows madwifi to operate correctly when using open or WEP protected modes without hostapd).

e7ccdf6be3 When IFF_MULTICAST was not enabled on the vap, we used to skip some filtering that prevents reception of your own multicast traffic. Then we would procede to ignore the fact that IFF_MULTICAST flag was disabled and send anyway. 
I've fixed the logic so that multicast is dropped, with an error when disabled.  I don't think this is a valid configuration.  Also, we don't skip the filtering logic so that our own multicast traffic doesn't come back to us (looking like a bridging loop).
