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.
with better performance and more complete ethtool support.
It does not support the link failover and network management
