In driver, we check if the chain ID has been registered, and goto chain is the
same as first matchall rule, if is not, then return error. Each rule need has
goto action except last chain.
I also have check about chain template, it can not set an action template for
each chain, so I think it's no use for our case. If this way to set rules is
OK, I will update the patch to do as this.

Because in QOS_PCP_DEI_MAP_CFG register, BIT(3) is DP value, BIT(2, 0) is QOS
value. QoS class=QOS_PCP_DEI_MAP_CFG[i].QOS_PC
P_DEI_VAL, i=8*DEI + PCP, so DP value need to be set BIT(3)
