*
* The software reset is done by
* - disabling the Rx and Tx state machine,
* - resetting the statistics module,
* - clear all other significant XMAC Mode,
* Command, and Control Registers
* - clearing the Hash Register and the
* Exact Match Address registers, and
* - flushing the XMAC's Rx and Tx FIFOs.
*
* Note:
* Another requirement when stopping the XMAC is to
* avoid sending corrupted frames on the network.
* Disabling the Tx state machine will NOT interrupt
* the currently transmitted frame. But we must take care
* that the Tx FIFO is cleared AFTER the current frame
* is complete sent to the network.
*
* It takes about 12ns to send a frame with 1538 bytes.
* One PCI clock goes at least 15ns (66MHz). Therefore
* after reading XM_GP_PORT back, we are sure that the
* transmitter is disabled AND idle. And this means
* we may flush the transmit FIFO now.
*
* Returns:
* nothing
