Nice, didn't know about that. But I fear whether this would always work for the 88X3310 vs 88X3310P, it is possible that this feature is only recognizable if the firmware in the PHY is already running.The ID registers aren't programmable and contain the proper IDs even if there isn't firmware loaded (I've had such a PHY here.)
Yes, but the macsec feature bit is in register MDIO_MMD_PMAPMD.MV_PMA_XGSTAT.12 (1.c001.12) But it says "This bit is valid upon completion of reset (1.0.15 = 0)", so it seems we can use this. :) Marek
