Mesh addressing issue

["Cedric VONCKEN" <cedric.voncken@xxxxxxxxx>]

                Dear all, 

I think I found an issue in mesh addressing. 
I used the compat-2012-06-14.

My network topology for the test is :
-----------------      -------------------   Wired LAN       -----------------
|MP1              |   |MP2                   |------------------| Computer      |
|192.168.4.1|    |192.168.4.253|                            |192.168.4.90 |
-----------------     -------------------                               ---------------

The MP1 is not bridged with any wired interface (The ip address is set directly on WLAN0 interface)
The MP2 is bridged with eth0 to offer link with a wired network (My computer is connected with the wired network).

If I try to ping from Computer to MP1.
      The ICMP request sent on WiFi (from MP2 to MP1) is a broadcast frame using a strange address format (3 address in 802.11 header + 1 address in mesh extension) . 
      The ICMP reply sent on wifi (from MP1 to MP2) is unicast frame using 6 addresses format.

Why the ICMP request is sent with address 1 set to broadcast (It was not the case for older compat-2011-08-25)?

If in MP1 I move the WLAN0 to a bridge with brctl (with no other interface), ICMP request are still sent with broadcast,
But 
 If I change the mac address of bridge interface, the ICMP request is now sent in unicast  format (using the 6 addresses formats) !

Best regards
