MODULE_DESCRIPTION("Packet Engines Yellowfin G-NIC Gigabit Ethernet driver");
I. Board Compatibility
This device driver is designed for the Packet Engines "Yellowfin" Gigabit
-Ethernet adapter. The G-NIC 64-bit PCI card is supported, as well as the
+Ethernet adapter. The G-NIC 64-bit PCI card is supported, as well as the
Symbios 53C885E dual function chip.
II. Board-specific settings
See Packet Engines confidential appendix (prototype chips only).
