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. > ---------------------------------------------------------- > You may want to re-map the interfaces so that they show up in a sane > order, there is a cluster of 8 ethernet ports, 4 per row.
