Group type ALL
The OpenFlow group type ALL is supported in both hardware and software. The capabilities are:
Executes all the action buckets in the group.
Supports groups in hardware, if each group bucket has only a single output port action.
NOTE:If a bucket has more than one instance of an output action or any other action, the bucket is installed on software instead of hardware.
Virtual ports other than OFPP_FLOOD are not supported in hardware group buckets.
Tunnel ports are not supported in group buckets of both hardware and software.
