I have a dual-port Mellanox ConnectX-3 (specifically MCX312A-XCBT),
which has a shared PHC. You can get them for less than $50 on
eBay/AliExpress. I had to upgrade the firmware on mine to get PTP
support. I haven't yet tried it as a boundary clock.

I also tried a secondhand dual-port Intel X550-T2, but that has a
separate PHC for each port.
