The PRU-ICSS sub-system available in TI AM57x/AM437x/AM335x SOCs is capable of
operating as HW offloaded L2 switch (STP/RSTP) with 2 PRU ports, by using Linux
switchdev.
The proposed changes are required to enable "bridge" config to get the support
for Linux switchdev, hardware offload features, and STP support to get a fully
functional L2 offloaded switch.
Thanks and Regards,
Parvathi.
