 > By design, the mesh forwarding engine always runs, regardless of the
 status of the kernel networking device. So when you issue an "ifconfig
 msh0 down" command, all that you are doing is telling the host to stop
 using the mesh interface and not to turn off the mesh forwarding engine in
 the firmware.

 conceptually, since they believe that ifconfig should really turn things
 on and off. In our case msh0 is only the means by which the host
 communicates with the communications processor on the wireless subsystem
 and the linux kernel interface semantics are just not enough for the host
 processor to exercise control over its partner.

 Thanks for the clarification. Makes much more sense now.
