renames matcdc to matcd.
This change is reported to work by two independent PR originators.
In the absence of further feedback on the freebsd-bugs list, we
may as well get this working for its two users.

- Modify the driver to poll the link state and positively set the
MAC to full or half duplex as needed. Previously, it was possible
for the MAC to remain in half duplex even though the PHY had negotiated
full duplex with its link partner, which would result in bursty
performance.
- Program some of the NatSemi's registers as specified by the datasheet.
The manual says these are necessary for "optimum perofrmance," though
a couple of them are marked as reserved in the register map. *shrug*
- Select the TX DMA burst size correctly for 10 and 100mbps modes.
Previously I was using 64 bytes in both modes, which worked in
100mbps mode, but resulting in spotty performance in 10mbps.
32 bytes works much better; without this change, the natsemi
chip yields piss poor performance at 10mbps.
With these fixes, the NatSemi chip finally performs to my satisfaction.
I should be merging the support for this controller into -stable shortly.
Phew.
In summary:
o This file has been moved to sys/compat/linux,
o Any MD syscalls in this file are moved to
linux_machdep.c in sys/i386/linux,
o Include directives, makefiles and config files
have been updated.
Make linux_to_bsd_sigset and linux_do_sigaction non-static.
Move linux_sigaction. linux_sigsuspend, linux_rt_sigsuspend,
linux_pause and linux_sigaltstack to MD code.
modify driver capability reporting format to list every audio format
seperately- required for above and because we could not previously indicate
that mono was unsupported.
there should be no functional impact.
Remove old DEVFS support fields from dev_t.
Make uid, gid & mode members of dev_t and set them in make_dev().
Use correct uid, gid & mode in make_dev in disk minilayer.
Add support for registering alias names for a dev_t using the
new function make_dev_alias(). These will show up as symlinks
in DEVFS.
Use makedev() rather than make_dev() for MFSs magic devices to prevent
DEVFS from noticing this abuse.
Add a field for DEVFS inode number in dev_t.
Add new DEVFS in fs/devfs.
Add devfs cloning to:
disk minilayer (ie: ad(4), sd(4), cd(4) etc etc)
md(4), tun(4), bpf(4), fd(4)
If DEVFS add -d flag to /sbin/inits args to make it mount devfs.
Add commented out DEVFS to GENERIC
reference count is initialised to zero to be more kosher.

something. It showed up as kobj functions not being called.
In any event, link in the pcic and pccard parts of the modules to work
around the problem for now.
that should be better.
The old code counted references to mbuf clusters by using the offset
of the cluster from the start of memory allocated for mbufs and
clusters as an index into an array of chars, which did the reference
counting. If the external storage was not a cluster then reference
counting had to be done by the code using that external storage.
NetBSD's system of linked lists of mbufs was cosidered, but Alfred
felt it would have locking issues when the kernel was made more
SMP friendly.
The system implimented uses a pool of unions to track external
storage. The union contains an int for counting the references and
a pointer for forming a free list. The reference counts are
incremented and decremented atomically and so should be SMP friendly.
This system can track reference counts for any sort of external
storage.
Access to the reference counting stuff is now through macros defined
in mbuf.h, so it should be easier to make changes to the system in
the future.
The possibility of storing the reference count in one of the
referencing mbufs was considered, but was rejected 'cos it would
often leave extra mbufs allocated. Storing the reference count in
the cluster was also considered, but because the external storage
may not be a cluster this isn't an option.
The size of the pool of reference counters is available in the
stats provided by "netstat -m".

has the side effect of detaching the children before I delete them.
When I put the last commits in a loop for loop it died after 5 or so
iterations. After this change, I lasted 50 before I stopped the test.
Add pcic_detach which removes all of the pcic's children.
This lets me load/unload pcic multiple times w/o having multiple
instances of each slot attached to pcic.
