Broadcom is a chip & SoC provider. You would need to contact system integrators to learn more about these class of features. It's similar for merchant silicon and switches. That's why companies like Arista are 90% sw engineers and have no ASIC teams. The market dynamics have mostly driven this per engineering and purchasing cadences.
Below is some older info from Cisco for some of their EAPs. I can't really make any claims about these features one way or another nor about the veracity of the information per the link.
