CPSW is mostly present on older TI's 32 bit SoCs and can support upto 2
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 at evm:~# ip link set eth0 type bridge_slave flood off mcast_flood off learning off
Error: bridge: bridge flag offload is not supported.
root at 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
