If it's two different X550 cards, I don't know. If it's two ports of the same card, the devices *do* share the same clock source (but you can't atomically set the registers for them, so it's not feasible to set it up as a proper boundary clock) Thanks, Jake ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
