sk98lin: remove obsolete driver
All the hardware supported by this driver is now supported by the skge driver. The last remaining issue was support for ancient dual port SysKonnect fiber boards, and the skge driver now does these correctly (p.s. sk98lin was always broken on these old dual port boards anyway).

- * Description:
- * After calling this function the descriptor rings and Rx and Tx
- * queues of this port may be reconfigured.
- *
- * It is possible to stop the receive and transmit path separate or
- * both together.
- *
- * Dir = SK_STOP_TX Stops the transmit path only and resets the MAC.
- * The receive queue is still active and
- * the pending Rx frames may be still transferred
- * into the RxD.
- * SK_STOP_RX Stop the receive path. The tansmit path
- * has to be stopped once before.
- * SK_STOP_ALL SK_STOP_TX + SK_STOP_RX
- *
- * RstMode = SK_SOFT_RST Resets the MAC. The PHY is still alive.
- * SK_HARD_RST Resets the MAC and the PHY.
- *
- * Example:
- * 1) A Link Down event was signaled for a port. Therefore the activity
- * of this port should be stopped and a hardware reset should be issued
- * to enable the workaround of XMAC Errata #2. But the received frames
- * should not be discarded.
- * ...

- * (transfer all pending Rx frames)
- * SkGeStopPort(pAC, IoC, Port, SK_STOP_RX, SK_HARD_RST);
- * ...
- *
- * 2) An event was issued which request the driver to switch
- * the 'virtual active' link to an other already active port
- * as soon as possible. The frames in the receive queue of this
- * port may be lost. But the PHY must not be reset during this
- * event.
- * ...
- * SkGeStopPort(pAC, IoC, Port, SK_STOP_ALL, SK_SOFT_RST);
- * ...
- *
- * Extended Description:
- * If SK_STOP_TX is set,
- * o disable the MAC's receive and transmitter to prevent
- * from sending incomplete frames
- * o stop the port's transmit queues before terminating the
- * BMUs to prevent from performing incomplete PCI cycles
- * on the PCI bus
- * - The network Rx and Tx activity and PCI Tx transfer is
- * disabled now.
- * o reset the MAC depending on the RstMode
- * o Stop Interval Timer and Limit Counter of Tx Arbiter,
- * also disable Force Sync bit and Enable Alloc bit.
- * o perform a local reset of the port's Tx path
- * - reset the PCI FIFO of the async Tx queue
- * - reset the PCI FIFO of the sync Tx queue
- * - reset the RAM Buffer async Tx queue
- * - reset the RAM Buffer sync Tx queue
- * - reset the MAC Tx FIFO
- * o switch Link and Tx LED off, stop the LED counters
- *
- * If SK_STOP_RX is set,
- * o stop the port's receive queue
- * - The path data transfer activity is fully stopped now.
- * o perform a local reset of the port's Rx path
- * - reset the PCI FIFO of the Rx queue
- * - reset the RAM Buffer receive queue
- * - reset the MAC Rx FIFO
- * o switch Rx LED off, stop the LED counter
- *
- * If all ports are stopped,

- * PRxQSize, PXSQSize, and PXAQSize has to be
- * configured for the specified port before calling this function.
- * The descriptor rings has to be initialized too.
- *
- * o (Re)configure queues of the specified port.
- * o configure the MAC of the specified port.
- * o put ASIC and MAC(s) in operational mode.
- * o initialize Rx/Tx and Sync LED
- * o initialize RAM Buffers and MAC FIFOs
- *
- * The port is ready to connect when returning.
- *
- * Note:
- * The MAC's Rx and Tx state machine is still disabled when returning.
- *
- * Returns:
- * 0: success
- * 1: Queue size initialization error. The configured values
- * for PRxQSize, PXSQSize, or PXAQSize are invalid for one
- * or more queues. The specified port was NOT initialized.
- * An error log entry was generated.
- * 2: The port has to be stopped before it can be initialized again.
