58 * There are two general 'types' of MX chips that we need to be
59 * concerned with. One is the original 98713, which has its internal
60 * NWAY support controlled via the MDIO bits in the serial I/O
61 * register. The other is everything else (from the 98713A on up),
62 * which has its internal NWAY controlled via CSR13, CSR14 and CSR15,
63 * just like the 21143. This type setting also governs which of the
64 * 'magic' numbers we write to CSR16. The PNIC II falls into the
65 * 98713A/98715/98715A/98725 category.
