25067ba265 Small fixes to sis(4):
- Remove sis_unit and use device_printf() and if_printf() instead.
- Use callout_init_mtx() for the callout.
- Remove spls.
- Fix locking for ifmedia to happen in the ifmedia handlers rather than in
  sis_ioctl().
- Log an error message if we fail to allocate any resources.  Perform
  cleanup if we fail to allocate any resources so that we don't leave
  a mutex hanging around.

695b15ca91 Fix agp_nvidia.c to behave more like the linux driver, fixing DRI on Radeon
9200 according to one responder.  The primary issue was not setting some bits
to say that the entries were active, but also fix one place where some memory
wasn't being used as volatile as it should.  While here, change some use of ffs
to a relatively short case statement, to make it more obvious what's going on.

3badacee8c Fix "struct ifnet" leaks when attach() fails in the middle, e.g.
when mii_phy_probe() or bus_setup_intr() fails.  For drivers that
call their detach() in this case, call if_free() there to cover
this case too.

4f867c2d17 When bus_alloc_resource_any() fails, dc_detach() is called and it
attempts to deallocate busdma tags and resources that haven't been
allocated yet, causing a panic every time a dc interface fails to
attach.  Fix by checking that we really have something to dealloc
before calling bus_dma*() functions.

dbc2a95f40 - Use m_defrag() instead of homerolling our own variant
tulip_mbuf_compress().  If we fail to allocate a new mbuf to copy the
  data into, put the mbuf back in the driver's send queue so that we can
  retry it later rather than throwing the packet away.
- Use m_devget() instead of doing it inline ourselves in the
  TULIP_COPY_RXDATA case.  If we fail to allocate an mbuf to copy the data
  into, don't forget about the original mbuf cluster.  The old code would
  lose the pointer and leak the cluster in that case.  Now it doesn't lose
  it but always sticks the original rx buffer back into the receive ring
  after trying to copy the data out and send it up the stack.  Also, if we
  fail to allocate a new mbuf to copy the data into, log an input error.
  Also, don't combine the priming case with the received-a-packet case to
  make the code flow a bit clearer and easier to follow.

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.

997452064e Various fixups to locking:
- Remove a lot of superfluous locking during attach.  There is no need
  to lock access to the driver until some other thread has a way of getting
  to it.  For ethernet drivers the other ways include registering an
  interrupt handler via bus_setup_intr(), calling ether_ifattach() to hook
  into the network stack, and kicking off a callout-driven timer via
  callout_reset().
- Use callout_* rather than timeout/untimeout.
- Break out of xl_rxeof() if IFF_DRV_RUNNING is clear after ifp->if_input
  returns to handle the case where the interface was stopped while we were
  passing a packet up the stack.  Don't call xl_rxeof() in xl_rxeof_task()
  unless IFF_DRV_RUNNING is set.  With these fixes in place, any
  outstanding task will gracefully terminate as soon as it gets a chance to
  run after the interface has been stopped via xl_stop().  As a result,
  taskqueue_drain() is no longer required in xl_stop().  The task is still
  drained in detach() however to make sure that detach() can safely destroy
  the driver mutex at the end of the function.
- Lock the driver lock in the ifmedia callouts and don't lock across
  ifmedia_ioctl() in xl_ioctl().

Note: glebius came up with most of (3) as well independently.  I took a
rather roundabout way of arriving at the same conclusion.

IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

c1b677aa80 The DC driver asks for an alignment of PAGE_SIZE for data buffers, but also
asks that each buffer be (2048 * 256) bytes long.  I suspect that alignment
isn't a real requirement since busdma only recently started honoring it.  The
size is also bogus.  Fix both of these and stop busdma from trying to
exhaust the system memory pool with bounce pages.

0afa9c9e2c Adjust TX threshold on every TX underrun. Some supported cards (8139-based)
can retransmit on TX underrun and set TOK in addition to TUND.  Also add a
check to prevent overflow of the addressable threshold.

This fixes some reports of rl(4) slowness, believed to be related to ALTQ
before.
