This was located in the ubsa driver, but should be moved into a separate
driver:
- 3G modems provide multiple serial ports to allow AT commands while the PPP
connection is up.
- 3G modems do not provide baud rate or other serial port settings.
- Huawei cards need specific initialisation.
- ubsa is for Belkin adapters, an Linuxy choice for another device like 3G.
Speeds achieved here with a weak signal at best is ~40kb/s (UMTS). No spooky
STALLED messages as well.
Next: Move over all entries for Sierra and Novatel cards once I have found
testers, and implemented serial port enumeration for Sierra (or rather have
Andrea Guzzo do it). They list all endpoints in 1 iface instead of 4 ifaces.

If you just config KERNEL as usual there should be no apparent changes, you'll get all chipset support code compiled in.
However there is now a way to only compile in code for chipsets needed on a pr vendor basis. ATA now has the following "device" entries:
atacore: ATA core functionality, always needed for any ATA setup
atacard: CARDBUS support
atacbus: PC98 cbus support
ataisa: ISA bus support
atapci: PCI bus support only generic chipset support.
ataahci: AHCI support, also pulled in by some vendor modules.
ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, atamarvell, atamicron, atanational, atanetcell, atanvidia, atapromise, ataserverworks, atasiliconimage, atasis, atavia; Vendor support, ie atavia for VIA chipsets
atadisk: ATA disk driver
ataraid: ATA softraid driver
atapicd: ATAPI cd/dvd driver
atapifd: ATAPI floppy/flashdisk driver
atapist: ATAPI tape driver
atausb: ATA<>USB bridge
atapicam: ATA<>CAM bridge
This makes it possible to config a kernel with just VIA chipset support by having the following ATA lines in the kernel config file:
device atacore
device atapci
device atavia
And then you need the atadisk, atapicd etc lines in there just as usual.
If you use ATA as modules loaded at boot there is few changes except the rename of the "ata" module to "atacore", things looks just as usual.
However under atapci you now have a whole bunch of vendor specific drivers, that you can kldload individually depending on you needs. Drivers have the same names as used in the kernel config explained above.

and bcmp are not the same thing. 'man bcmp' states that the return is
"non-zero" if the two byte strings are not identical. Where as,
'man memcmp' states that the return is the "difference between the
first two differing bytes (treated as unsigned char values" if the
two byte strings are not identical.
So provide a proper memcmp(9), but it is a C implementation not a tuned
assembly implementation. Therefore bcmp(9) should be preferred over memcmp(9).
compile these with -mcpu=ultrasparc (which is the hard-coded default

Split the driver into the core functionality part (sys/dev/tsec/if_tsec.c) and
the bus attachment (sys/dev/tsec/if_tsec_ocp.c).
This lets better integrate and maintain the driver in other environments with
different attachment abstractions (there is at least one other FreeBSD port --
MPC83xx -- which uses this TSEC driver, but with different local bus model
i.e. some OF derivative). While there, clean up and fix minor cosmetics.

(1) Abstract interpreter vnode labeling in execve(2) and mac_execve(2)
so that the general exec code isn't aware of the details of
allocating, copying, and freeing labels, rather, simply passes in
a void pointer to start and stop functions that will be used by
the framework. This change will be MFC'd.
(2) Introduce a new flags field to the MAC_POLICY_SET(9) interface
allowing policies to declare which types of objects require label
allocation, initialization, and destruction, and define a set of
flags covering various supported object types (MPC_OBJECT_PROC,
MPC_OBJECT_VNODE, MPC_OBJECT_INPCB, ...). This change reduces the
overhead of compiling the MAC Framework into the kernel if policies
aren't loaded, or if policies require labels on only a small number
or even no object types. Each time a policy is loaded or unloaded,
we recalculate a mask of labeled object types across all policies
present in the system. Eliminate MAC_ALWAYS_LABEL_MBUF option as it
is no longer required.

The last half year I've been working on a replacement TTY layer for the
FreeBSD kernel. The new TTY layer was designed to improve the following:
- Improved driver model:
The old TTY layer has a driver model that is not abstract enough to
make it friendly to use. A good example is the output path, where the
device drivers directly access the output buffers. This means that an
in-kernel PPP implementation must always convert network buffers into
TTY buffers.
If a PPP implementation would be built on top of the new TTY layer
(still needs a hooks layer, though), it would allow the PPP
implementation to directly hand the data to the TTY driver.
- Improved hotplugging:
With the old TTY layer, it isn't entirely safe to destroy TTY's from
the system. This implementation has a two-step destructing design,
where the driver first abandons the TTY. After all threads have left
the TTY, the TTY layer calls a routine in the driver, which can be
used to free resources (unit numbers, etc).
The pts(4) driver also implements this feature, which means
posix_openpt() will now return PTY's that are created on the fly.
- Improved performance:
One of the major improvements is the per-TTY mutex, which is expected
to improve scalability when compared to the old Giant locking.
Another change is the unbuffered copying to userspace, which is both
used on TTY device nodes and PTY masters.
Upgrading should be quite straightforward. Unlike previous versions,
existing kernel configuration files do not need to be changed, except
when they reference device drivers that are listed in UPDATING.

In order to CATER this, DDB buffered output can be choosen at compile
time through the option DDB_BUFR_SIZE=nbytes where nbytes choose the size
of the buffer (suggested size is 128 bytes), which should be manually
specified in any interested config file.

virtualization work done by Marko Zec (zec@).
This is the first in a series of commits over the course
of the next few weeks.
Mark all uses of global variables to be virtualized
with a V_ prefix.
Use macros to map them back to their global names for
now, so this is a NOP change only.
We hope to have caught at least 85-90% of what is needed
so we do not invalidate a lot of outstanding patches again.
