23 Dual mac mode
26 - The new (cpsw_new.c) driver is operating in dual-emac mode by default, thus
27 working as 2 individual network interfaces. Main differences from legacy CPSW
30 - optimized promiscuous mode: The P0_UNI_FLOOD (both ports) is enabled in
32 So, Ports in promiscuous mode will keep possibility of mcast and vlan
34 to the same bridge, but without enabling "switch" mode, or to different
36 - learning disabled on ports as it make not too much sense for
37 segregated ports - no forwarding in HW.
