- * I have tried to make it clear what is device specific code
- * and what code supports the general BSD ethernet interface. d-link
- * specific code is preceded by a line or two of
- * "d-link 600 ON; d-link 600 ON; d-link 600 ON; d-link 600 ON"
- * and followed by a line or two of
- * "d-link 600 OFF; d-link 600 OFF; d-link 600 OFF; d-link 600 OFF"
- *
- * The main routines that do device specific processing are:
- * de6cintr - interrupt dispatcher
- * de6crcv - rcv packets and switch to new buffers
- * de6cxmt - xmt packet and wait for xmtbusy to clear
- * de6calive - probe for device
- * de6cinit - device initialization
- * de6cintoff - turn it off.
- * There are a couple of interesting macros at the head of this
- * file and some support subroutines at the end.
- *
- * Lastly, to get decent performance on i386SX class machines, it
- * was necessary to recode the read and write d-link memory routines in
- * assembler. The deread and dewrite routines that are used are in
- * if_de6s.s
- *
- */
-
-/* Questions:
-
- Make sure that iopl maps 378, 278 and 3bc.
-
- If you set command w/o MODE and page bit, what happens?
-
- Could I get xmt interrupts; currently I spin - this is not an issue?
-
- enable promiscuous?
-
- Can you assert TXEN and RXen simulatneously?
