History
John Baldwin f8190d8dc8 Major rototill of this driver to add FreeBSD bus-dma support: 
- Allocate arrays of metadata for the descriptors in the rx and tx rings
  and change the ring pointers to walk the metadata array rather than the
  actual descriptor rings.  Each metadata object contains a pointer to its
  descriptor, a pointer to any associated mbuf, and a pointer to the
  associated bus_dmamap_t in the bus_dma case.  The mbuf pointers replace
  the tulip_txq and tulip_rxq local ifqueue's in the softc.
- Add lots of KTR trace entries using a local KTR_TULIP level which
  defaults to 0, but can be changed to KTR_DEV at the top of the file
  when debugging.
- Rename tulip_init(), tulip_start(), tulip_ifinit(), and tulip_ifstart()
  to tulip_init_locked(), tulip_start_locked(), tulip_init(), and
  tulip_start(), respectively, to match the convention in other drivers.
- Add a TULIP_SP_MAC() macro to encode two bytes of the MAC address into
  the setup buffer and use that in place of lots of BYTE_ORDER #ifdef's.
  Also, remove an incorrect XXX comment I added earlier, the driver was
  correct (at least it does the same thing dc(4) does).  TULIP_SP_MAC
  was shamelessly copied from DC_SP_MAC() in dc(4).
- Remove the #ifdef'd NetBSD bus-dma code and replace it with FreeBSD
  bus-dma code that not only compiles but even works at runtime.
- Use callout_init_mtx() instead of just callout_init().
- Correct the various wrapper macros for bus_dmamap_sync() for the rx
  and tx buffers to only ask for the sync ops that they actually need.
- Tidy the #ifdef TULIP_COPY_RXDATA code by expanding an #ifdef a bit
  so it becomes easier to read at the expense of a couple of duplicated
  lines of code.  Also, use m_getcl() to get an mbuf cluster rather than
  MGETHDR() followed by MCLGET().
- Maintain the ring free (ri_free) count for the rx ring metadata since
  we no longer have tulip_rxq.ifq_len around to indicate how many mbuf's
  are currently in the rx ring.
- Add code to teardown bus_dma resources when attach fails and generally
  fixup attach to do a better job of cleaning up when it fails.  This
  gets us a good bit closer to possibly having a detach method someday
  and making this driver an unloadable module.
- Add some functions that can be called from ddb to dump the state of
  a descriptor ring and to dump the state of an individual descriptor.
- Various comment grammer and spelling fixes.

I have bus-dma turned on by default, but I've left the non-bus-dma code
around so that it can be turned off to aid in debugging should any problems
turn up later on.  I'll be removing the non-bus-dma code in a subsequent
commit.
