throttling, neglecting to do this kept the sysctls from appearing.
Attach an acpi_throttle device to each CPU that supports it.
Don't add a device if the P_BLK is invalid or if _PTC is not present.
This removes extraneous probe/attach failure messages on some machines.
Make the cpu throttle state local to the softc to account for partial
successes when changing the clock rate on MP machines.
When reading the bodies of Zip archive entries, request a minimum of 1
byte, rather than a minimum of the full entry size. This is faster
(since it does not force the decompression layer to combine reads) and
works around a bug in the "none" decompression handler (which I'm
testing a separate fix for now). I've also renamed "bytes_read" to
"bytes_avail" in several places to more accurately reflect that the
value returned from (a->compression_read_ahead) is the number of bytes
available, not necessarily the number of bytes requested.
(padding) entries, extract inode value from PX entry, recognize SP and
ST (start/end of SUSP extensions).
I don't enforce SP yet, as I've seen CDROMs which use Rockridge
extensions but don't have the SP record (which is officially
required).
The ISO9660 support is now mature enough to extract FreeBSD
distribution CDROMs created with mkisofs.
for nodes hanging off of Central (untested), FireHose (untested) and
PCI (tested) busses.
- Add an additional parameter to OF_decode_addr() which specifies the
index of the register bank to decode.
These should allow to eventually add support for the Z8530 hanging off of
FireHose to uart(4) and to write support for PCI-based graphics adapters.

o Add a fallback location for the MAC address. Most of the early ne2000
PC Cards were built from the same parts, so most of them have the same
address in the CIS to grab the MAC from. Use this address as our
fallback if we don't find anything better.
o Add printf, in bootverbose, noting the MAC addresses that we find along
the way.
# Better sanity checking of the MAC address is needed. Will have to
# investigate using/creating a centralized function to do this as a number
# of other PC Card drivers each have their own ad-hoc tests.
a definite setup was broken: two ng_ksockets are connected to each other,
connect()ed to different remote hosts, and bind()ed to different local
interfaces. In this case one ng_ksocket is fooled with tag from the other
one.
Put node id into tag. In rcvdata method utilize tag only if it has our
own id inside or id equals zero. The latter case is added to support
packets send by some third, not ng_ksocket node.

1. Dependency on netgraph module was broken (wrong version).
2. Netgraph node type was never destroyed on unload. This
was masked by problem #1.
Fixed both by using NETGRAPH_INIT(). Now netgraph node type
is created on module load, as in the rest of netgraph modules.
This information will be very useful for people who are tuning applications
which have a dependence on IPC mechanisms.
