- * SkGeStopPort() - Stop the Rx/Tx activity of the port 'Port'.
- *
- * 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.
- * ...
- * SkGeStopPort(pAC, IoC, Port, SK_STOP_TX, SK_HARD_RST);
- * (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,
- * o reset the RAM Interface.
- *
- * Notes:
- * o This function may be called during the driver states RESET_PORT and
- * SWITCH_PORT.
