> 2. The action flags are optimized to be the limited bits the flow needs.
> 3. The bits members are reorganized to align with bytes.

> 2. Fdir handle is converted to one bit to save the pointer to another list.
> 3. Metadata handle is converted to uint32_t type as indexed.
> 4. Remove the duplicated RSS member in rte flow.
> 5. The bit members are reorganized to align with bytes.

> Some extra optimizations:

> 2. Allocate rte flow from indexed memory pool.
> 3. Split RSS type, level, key to common memory as they are not required
