Description
Magic Packet Enable, set to enable Magic Packet Mode
Sleep mode and MPE mode can be used seperately. When Sleep and MPE are both set, the Sleep mode dominate
MPE, i.e., no magic packet can be detected since both TX and RX channel are shut off in sleep mode. On the
detection of magic packet, a negative pulse will be asserted on PME# pin on PCI bus, LANWAKE pin will be
asserted high and EXSTART# pin is driven low and stay low even after PCI reset is asserted. EXSTART# pin can
be reset by device driver.
