2 * New driver for Marvell Yukon chipset and SysKonnect Gigabit
3 * Ethernet adapters. Based on earlier sk98lin, e100 and
4 * FreeBSD if_sk drivers.
5 *
6 * This driver intentionally does not support all the features
7 * of the original driver such as link fail-over and link management because
8 * those should be done at higher levels.
