3 * This is a driver for SMSC's 91C9x/91C1xx single-chip Ethernet devices.
49 * 29/09/03 Russell King - add driver model support
50 * - ethtool support
51 * - convert to use generic MII interface
52 * - add link up/down notification
53 * - don't try to handle full negotiation in
55 * - clean up (and fix stack overrun) in PHY
124 * Use power-down feature of the chip
