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.
Excellent. This is very helpful James. I've ordered a MCX312A and B and
will compare both here. I'll share my results here soon. If you have a
chance please also share the firmware version you're currently using on
your NIC.
With my Intel NIC I could get the BC config working but I needed to set
the twoStepFlag to 1. Otherwise I was getting this for both ports:
ptp4l[1040.180]: ioctl SIOCSHWTSTAMP failed: Numerical result out of range
Sync quality wasn't great as expected though. I'll repeat with the
Mellanox once I have them here.
Thanks
Andre
