similar to the PNIC I (supported by the pn driver). In fact, it's really a Macronix 98715A with wake on LAN support added. According to LinkSys, the PNIC II was jointly developed by Lite-On and Macronis. I get the feeling Macronix did most of the work. (The datasheet has the Macronix logo on it, and is in fact nearly identical to the 98715 datasheet, except for the extra wake on LAN registers.) In any case, the PNIC II works just fine with the Macronix driver. The changes are: - Move PCI ID for the PNIC II from the pn driver to the mx driver. - Mention PNIC II support in mx.4. - Mention PNIC II support in RELNOTES.TXT and HARDWARE.TXT.
