+ This driver support the Marvell Yukon or SysKonnect SK-98xx/SK-95xx
+ and related Gigabit Ethernet adapters. It is a new smaller driver
+ driver with better performance and more complete ethtool support.
+
+ It does not support the link failover and network management
+ features that "portable" vendor supplied sk98lin driver does.
