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.
