The current tc_add_flow() and tc_del_flow() use hardware L3 & L4 filters as offloading. The number of L3/L4 filters is read from L3L4FNUM field from MAC_HW_Feature1 register and is used to alloc priv->tc_entries[]. For RX frame steering based on VLAN priority offloading, we use MAC_RXQ_CTRL2 & MAC_RXQ_CTRL3 registers and all VLAN priority level can be configured independent from L3 & L4 filters.
