- Remove form feed characters.
- Fixup style of function declarations.
- Assume that an mbuf cluster is big enough to hold an ethernet frame.
(This should really be using m_defrag(), but this diff is just simple
changes for now.)
- 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.
It is the binary equivalent to strstr(3).

This allows witness_checkorder() to use isitmychild() instead of
the much more expensive isitmydescendant() to check for valid lock
ordering.
Don't do an expensive tree walk to update the w_level values when
the tree is updated. Only update the w_level values when using the
debugger to display the tree.
Nuke the experimental "witness_watch > 1" mode that only compared
w_level for the two locks. This information is no longer maintained
at run time, and the use of isitmychild() in witness_checkorder
should bring performance close enough to the acceptable level that
this hack is not needed.

Note, that when cron(8) cannot create pidfile, it'll exit. I didn't
changed this behaviour, but its better to ignore errors other than
EEXIST, so daemon can be started on systems where /var/ file system
doesn't support locking (like NFS without rpc.lockd(8)).
Now this flag can be set, or not set, for memory-backed
file systems on individual basis, as illustrated by the
rc.conf(5) variables tmpmfs_flags and varmfs_flags. The
flag is set for those FS'en by default, in /etc/defaults/rc.conf,
in order to stay compatible with the old rc.subr behaviour.
