Different board types (ie. FPGA, HDK and DVP/EVB) require slightly
different init configuration options. Since we cannot probe the type
of board from the actual hardware, we need to pass it as an option
during module load.
This patch adds a module parameters that accepts the 3 different board
types, with DVP/EVB as the default, and uses this value where needed.

When any interface goes down, it could be the one that we
were doing a remain-on-channel with. We therefore need to
cancel the remain-on-channel and flush the related work
structs so they don't run after the interface has been
removed or even destroyed.
It's also possible in this case that an off-channel SKB
was never transmitted, so free it if this is the case.
Note that this can also happen if the driver finishes
the off-channel period without ever starting it.

Mesh station that joins an MBSS is reachable using mesh portal with 6
address frame by mesh stations from another MBSS if these two different
MBSSes are bridged. However, if the mesh station later moves into the
same MBSS of those mesh stations, it is unreachable by mesh stations
in the MBSS due to the mpp_paths table is not deleted. A quick fix
is to perform mesh_path_lookup, if it is available for the target
destination, mpp_path_lookup is not performed. When the mesh station
moves back to its original MBSS, the mesh_paths will be deleted once
expired. So, it will be reachable using mpp_path_lookup again.
