Subject: Mesh HWMP: PREQ node queue full

Hi linux-wireless list,

I'm testing the mesh capabilities (specifically, MPP) of the latest kernel
(3.0). My driver is ath9k on AR9390 chip. My two APs are configured
identically as follows:

----- mesh.sh start
#!/bin/sh

iw dev wlan1 interface add mesh0 type mp mesh_id wavmesh
ip link set mesh0 addr $(cat /etc/network/mesh0.mac)

brctl addbr br0
brctl addif br0 eth0
brctl addif br0 mesh0

ifconfig mesh0 down up
ifconfig eth0 0.0.0.0
ifconfig br0 up
----- mesh.sh end

When transferring traffic from a machine behind one eth0 to a machine behind
the other eth0, I see the following on the console (of both APs, only
different MACs):

Mesh HWMP: sending PREP to 02:92:ca:39:48:72
Mesh HWMP: sending PREQ to 02:92:ca:39:48:72
Mesh HWMP: received PREP from 02:92:ca:39:48:72
Mesh HWMP: received PREQ from 02:92:ca:39:48:72
Mesh HWMP: PREQ is for us
Mesh HWMP: replying to the PREQ
Mesh HWMP: sending PREP to 02:92:ca:39:48:72
mesh_queue_preq: 40 callbacks suppressed
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full
Mesh HWMP: PREQ node queue full

Any suggestion?

Hi Javier,

This is the MAC address of the mesh gate (i.e. the other AP). What is
"external proxied node"?

Baruch,

Thanks for reporting. Is 02:92:ca:39:48:72 the address of the mesh
gate or the address of the external proxied node?

We'll look into it.

The node outside the mesh you were trying to reach.
