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
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.
