- Closing the audio device should stop recording.
- Manipulating the pause function could accidentally start playing or recording.
- AUDIO_FLUSH could accidentally start playing or recording.
- guard against synchronous I/O completion
- avoid race conditions
- use bgetvp/brelvp to properly maintain the vnode holdcount
and clean/dirty buffer lists.

does a "restore data pointers" when reselected after disconnecting in
the middle of a DMA transfer). The driver needs a different way to know
which script to continue the DMA transfer. The message-in for the "restore
data pointers" loses the original "resume" script, and the driver would
attempt to continue the DMA transfer at the beginning of the current DMA
chunk, rather than at the point the disconnect occured. The result was a
spurious console message, and a trashed filesystem.
clobbers my SMC. Now I can really use a generic kernel with my SMC @0x300.
This change has been tested on various machines with ne2000 and 3c509 baords.

to be reloaded every time it is checked. This avoids a condition where
it can be cached in a register in such a way that updates to the flags in
an interrupt handler to not be noticed, which in turn causes the process
doing the i/o to sleep forever. Bug report and suggested fix from
Hiroshi HORIMOTO <horimoto@cs-yuugao.cs.sist.ac.jp>, PR $4460.
nullbuf (used to pad packets < ETHER_MIN_SIZE) is used for all tl
interfaces. Allocates only once, and never deallocate it (as we can't say
if another instance of the driver is interface is using it).
i/o-mapped space to always be used), we discover that at least one
ThunderLAN interface can't read the EEPROM properly if memory-mapped
access is used. Kludge around this for now by "prefering" i/o space.

NE2000 clones).
- Do PCI space configuration like the other drivers. In particular,
don't _disable_ the space we're not using because some lame firmware
implementations might not reenable it on warm boot. Also, prefer
memory space always.
- Make match and info-gathering in attach table-driven.
- Rearrange things a bit to be a bit more visually pleasing during boot.
Also, fixup some #include problems.
