#861: Nodes with different MAC address prefix cannot form a mesh.

Type: defect | Status: new
Priority: high | Milestone: BTest-3
Component: wireless | Keywords: mesh
----------------------+-----------------------------------------------------
In the firmware, a condition for a packet to be considered mesh traffic is
that
the source MAC address has the same prefix as our MAC address. The reason
for
this is that we cannot use mesh frame types (type 0x3) for the mesh. There
is a
hardware limitation in the MAC controller that prevents us from using this
new
type, and we are using WDS frames instead. To discriminate mesh from
legitimate WDS frames, we currently inspect the address prefix.
The length of the prefix is currently set to 4, which means that two
laptops that differ in the 4th byte of the mac address will not be able to
communicate in the mesh.
