* Bits for the SDRAM controller
* -----------------------------
*

* the 2nd Clock after ACTIVE command (CAS Latency = 2). If set to 1 the SDRAM
* controller asserts TA# on the 3rd Clock after ACTIVE command (CAS Latency = 3).
* RCD: RCD ACTIVE to READ or WRITE Delay (Ras to Cas Delay). If cleared 0 (default)
* tRCD of the SDRAM must equal or less 25ns. If set to 1 tRCD must be equal or less 50ns.
* WREC:Write Recovery. If cleared 0 (default) tWR of the SDRAM must equal or less 25ns.
* If set to 1 tWR must be equal or less 50ns.
* RP: Precharge Command Time. If cleared 0 (default) tRP of the SDRAM must equal or less
* 25ns. If set to 1 tRP must be equal or less 50ns.
* RC: Auto Refresh to Active Time. If cleared 0 (default) tRC of the SDRAM must equal
* or less 75ns. If set to 1 tRC must be equal or less 100ns.
* LMR: Bit to set the Mode Register of the SDRAM. If set, the next access to the SDRAM
* is the Load Mode Register Command.
* IIP: Init in progress. Set to 1 for starting the init sequence
* (Precharge All). As long this bit is set, the Precharge All is still in progress.
* After command has completed, wait at least for 8 refresh (200usec) before proceed.

likes, as long as its environment is kept intact (like the BIOS

driver and even the FreeBSD driver (what a piece of crap!) - and
eventually spotted the nasty thing: the transmit routine was acknowledging
each and every interrupt pending, including the RxOverrun and RxFIFIOver
interrupts. This confused the RTL8139 thoroughly. It destroyed the
interrupts. This confused the RTL8139 thoroughly. It destroyed the
Rx ring contents by dumping the 2K FIFO contents right where we wanted to
get the next packet. Oh well, what fun.

Drastically simplified error handling. Basically, if any error
in transmission or reception occurs, the card is reset.
Also, pointed all transmit descriptors to the same buffer to
save buffer space. This should decrease driver size and avoid
save buffer space. This should decrease driver size and avoid
corruption because of exceeding 32K during runtime.

rtl_poll was quite broken: it used the RxOK interrupt flag instead
of the RxBufferEmpty flag which often resulted in very bad
transmission performace - below 1kBytes/s.
