cards. At the present time, there's only one bridge driver for the
ARM9 based Atmel AT91RM9200.
tasks. Since the host controllers rely on tasks to process transfer
timeouts, if a synchronous transfer from a driver was invoked from
a task and timed out, it would never complete because the single
task thread was stuck performing the synchronous transfer so couldn't
process the timeout.
This affected the axe, udav and ural drivers.

long being DMA'ed 2 (or 1) bytes past the end of the mbuf and corrupting
random kernel memory. I had forgotten about the 2 bytes of implict
padding the firmware assumes.

- Use bus_dmamap_load_mbuf_sg() to eliminate the need for the callback and
all of the extra bookkeeping associated with it.
- Eliminate the bce_dmamap_arg structure and streamline the memory allocation
routines to not need it. This does change some of the debugging messages.
- Refactor the loop that fills the buffer descriptor so that it can be done
with a single set of logic in a single loop instead of two sets of logic.
- Eliminate the need to cache and pass descriptor indexes between the start
loop and the encap function.
- Change the start loop to always check the ifnet sendq for more work.
This significantly helps the driver withstand large UDP workloads, though
it's still not perfect. I suspect the remaining work lies with handling
the OACTIVE flag, and also in possibly streamlining the interrupt handler
some. It is, however, nearly on par with the other popular gigabit drivers
in terms of stability now.
- Add entries in the uscanner.4 man page (along with missing 3500).

will fix a problem where you boot w/ the default of autoselect, but then
set the speed to 100/full, the switch will keep the autoselect/100/full
negotiation... This will continue to work till someone resets the switch
or unplugs the cable resulting in the switch failing to autoneg and falling
back to 100/half, causing a hard to track down duplex mismatch..

- Add support for the Conexant Waikiki/CX20551-22, found
in most Toshiba P100 series laptops. Despite of growing
urban legend of "unsupported Conexant", this codec is fully
supported in this driver.
Note: Toshiba P100 has broken (acpi) BIOS, thus rendering
its soundchip useless. Please disable ACPI, or get
BIOS updates (if any).

- Parser cleanups to handle possible oss/mixer collision. Found
after parsing Conexant Waikiki nodes.
- Increase resilient against resource failure during attach/detach.
- Implement simple config through hint.pcm.<unit>.config. Supported
options:
gpio0 (default on Acer), gpio1, gpio2, softpcmvol,
fixedrate (default), forcestereo (default)
* Option prefixed with "no" (such as "nofixedrate") will do
the opposite.
* Options can be separated using space " " or comma ",".
* The "no" option will take precedence over anything else.
Example:
hint.pcm.0.config="gpio2,nofixedrate,noforcestereo,nogpio0,softpcmvol"
hint.pcm.0.config="softpcmvol noforcestereo"
