First attempt at o11s. Need hints.

[Steve Brown]

I have two machines, both running current wireless-testing. One has a 
b43 supported minipci radio and the other a zd1211rw supported usb 
radio. Both are listed to work for 11s mesh.

I have CONFIG_MAC80211_MESH=y and CONFIG_MAC80211_VERBOSE_MPL_DEBUG=y.

The commands to set things up on each machine:

iw dev wmaster0 interface add mesh type mp mesh_id 1234
iwconfig mesh channel 11
ifconfig mesh 192.168.10.50

and on the other,

iw dev wmaster0 interface add mesh type mp mesh_id 1234
iwconfig mesh channel 11
ifconfig mesh 192.168.10.51

Whether I use the master device or the wlanx interface makes no 
difference. There no complaints issuing the commands.

I have build a patched wireshark. It records exactly 11 frames from each 
machine. A copy is attached. Neither machine responds to the other. 
There is no mac80211 debug output, but some from b43, so I'm sure that 
kernel.debug is getting to the log.

The command "iw dev mesh station dump" comes up empty.

I'm not sure what kind of negotiation sequence to expect. It doesn't 
matter which interface comes up first nor whether both come up at the 
same time.

I've probably done something really dull. If so, hints are welcome. If 
something appears broken, tell me what it is. I will characterize it and 
post it to linux-wireless.

Lastly, is there anything available in the public domain that describes 
the current frame formats and other details of the protocol? Google 
returns lots of mostly conflicting info.

Thanks,

Steve
