It's nice to see contributions from Synopsys!
Have you seen the (relatively newly introduced) common framework for
Frame Preemption and the MAC Merge layer?
https://docs.kernel.org/networking/ethtool-netlink.html#mm-get
https://man7.org/linux/man-pages/man8/ethtool.8.html
https://man7.org/linux/man-pages/man8/tc-mqprio.8.html # "fp" option
https://man7.org/linux/man-pages/man8/tc-taprio.8.html # "fp" option
I think it would be valuable if the stmmac driver would also use it, so
it could support openlldp and pass the selftest at
https://github.com/torvalds/linux/blob/master/tools/testing/selftests/net/forwarding/ethtool_mm.sh
