1534 * Table of mapping schemes from port number to external number.

1537 * a cable assembly attached to a module inserted in an SFP+/QSFP+ cage on
1538 * the board, or fixed to the board (e.g. 10GBASE-T magjack on SFN5121T

1543 * port mapping (n:1)
1546 * External port number (1-based)
1548 * fixed (1:1) or cable assembly (1:m)

1554 * as visibly annotated on the board or back panel. This table describes
1555 * how to determine which external cage/magjack corresponds to the port
1556 * numbers used by the driver.
1558 * The count of consecutive port numbers that map to each external number,
1559 * is determined by the chip family and the current port mode.
1561 * For the Huntington family, the current port mode cannot be discovered,
1562 * but a single mapping is used by all modes for a given chip variant,
1563 * so the mapping used is instead the last match in the table to the full
1564 * set of port modes to which the NIC can be configured. Therefore the
1565 * ordering of entries in the mapping table is significant.
