I used to maintain a list of hardware, but I gave that up years ago when the number of products became too large. Nowadays most new MACs have PTP support. The easiest way to find out your MAC's capabilities is: ethtool -T eth0 For PHYs, the main issue is that the Linux networking stack doesn't treat MACs and PHYs equally. If you really need to use a PTP PHY, then you will likely have to configure and even patch your kernel specifically for your hardware.

[Linuxptp-users] PTP client selecting source IP address when NIC configured for multiple IPs
Hello, Use Case: Our application is running in a N:1 redundancy configuration. Each primary server is configured with a "real" IP address and a virtual IP address. The backup is configured with a real IP address only. The real IP address is intended for communications to the server regardless of its state (active or inactive); the virtual IP address is assigned to the server when it is active only. Besides management protocols, it is desired for PTP to use the real IP address in order to reduce impact to the grandmaster when the primary server changes its state from active to inactive (Failover) or inactive to active (Recovery). When the interface is assigned an IPv4 address, PTP uses the real IP address. When IPv6, PTP uses the virtual IP address. Our customer is using IPv6 and wants the real IP to be used. We suspect that without PTP specifying, Linux (RHEL9) is choosing the source IP in an indiscriminate manner. We could not find a PTP configuration to choose the source IP when using unicast to communicate to the master. Requests: I am seeking confirmation that linuxPTP does not allow the user to specify the slave's source IP for unicast communications. And second, if this is something the PTP development community would consider adding to PTP configuration.
