PHYAD 0 for ports 4 - 7 seems a bit strange to me. Do you have the sources of
the
kernel you're running on those machines ? If so, could you look at
int cvmx_helper_board_get_mii_address(int ipd_port) in cvmx-helper-board.c ?
It contains a large switch statement. case CVMX_BOARD_TYPE_CUST_WSX16: is what
I'm
interested in.

Thanks,
