CPSW is mostly present on older TI's 32 bit SoCs and can support upto 2
external ports.

AM65 NUSS is next generation multi port switch IP (up to 8 external
ports) present on TI's newer 64 bit platform. It also has different DMA integration and has native HW support to work as both Multi Mac and Switch mode.

Sorry, I have not done extensive testing but tried couple of cmds. Those worked as expected:

root@evm:~# ip link set eth0 type bridge_slave flood off mcast_flood off learning off                                                  
Error: bridge: bridge flag offload is not supported.

root@evm:~# ip link set eth0 type bridge_slave  mcast_flood off
[ 65.025285] am65-cpsw-nuss 8000000.ethernet eth0: BR_MCAST_FLOOD: 0 port 1
