Hi,
I am using mesh network. Kernel ver 3.12.2.
Scenario: When 2 wired and 1 wireless boards are forming mesh network,
packets are dropped
because of 'iw mesh0 mpath dump" changed entry.
This case no Issue:
// Own mac X:X:X:14:17:AD -------> A wireless
X:X:X:10:3f:ad -------> B wired
X:X:X:14:18:01 -------> C wired
# iw mesh0 mpath dump
DEST ADDR NEXT HOP IFACE
X:X:X:10:3f:ad X:X:X:10:3f:ad mesh0 //All traffic travels
through this mesh peer
X:X:X:14:18:01 X:X:X:14:18:01 mesh0
# iw mesh0 mpath dump //Changed packet is dropped because of mpath entry
DEST ADDR NEXT HOP IFACE
X:X:X:10:3f:ad X:X:X:14:18:01 mesh0
X:X:X:14:18:01 X:X:X:14:18:01 mesh0
Here the station peer C blocked station B, so drops all the packet
coming from station B.
Can someone please help me?
Anything required please feel free to mail me.

Are both B and C wired _and_ wireless, and A is wireless only? So B and C
are mesh portals, to the same wired network?
If that's the case you need to enable STP on the bridges.
