8 port ethernet switch with copper/fiber capabilities and PTP

I need a solution for a board with 8 100/10 ethernet ports (with copper/fiber switching capabilities, PTP and idealy also with PRP, HSR protocol capabilities). I've found KSZ8999I switch, but I think it doesn't support PTP (according to the datasheet it doesn't). I also looked at KSZ8463 switch, it supports PTP but  it has only 2 ports. So, I didn't manage to find an ethernet switch that i need. Do such switches even exist and where can i find them? I also thought about decisions based on FPGA or ethernet controllers… Could somebody give me a clue for a more chip and easy solution?
