Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
|
* 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.
