Register _childdetached methods with drivers that attach children.
Wait to set child references to NULL there, instead of doing that
in the detach method.
Replace many uses of USB_DECLARE_DRIVER() with CFATTACH_DECL2().
the opportunity to handle an ioctl before generic ifioctl handling
occurs. This will ease extending the kernel and sharing of code
between drivers.
First steps: Make the signature of ifioctl_common() match struct
ifinet->if_ioctl. Convert SIOCSIFCAP and SIOCSIFMTU to the new
ifioctl() regime, throughout the kernel.
host controller implementations, start with two little functions
which fake up string descriptors (which were inconststent, language
table fetching didn't interoperate with other code in the tree)
individually then waiting for it to become stable, power them up all
at once and then delay. Don't even bother delaying if we are a root hub,
as this is handled separately in the event thread. From OpenBSD.

uhmodem: device driver for huawei 3G wireless modem
* what it is?
A device driver for huawei 3G wireless modem, E220 and its valiations.
The devices are very simuler to ubsa device, but they need special care
to use as modem device.
This patch introduce "uhmodem (USB Huawei modem)" for the devices.
A uhmodem device has two com devices and one USB mass strage device.
The driver enable to use all of them.
* dmesg:

handling, ether_mediastatus() and ether_mediachange(). Check for
a non-ENXIO error return from mii_mediachg(). (ENXIO indicates
that a PHY is suspended.)
This patch shrinks the source code size by 979 lines. There was
a 5100-byte savings on the NetBSD/i386 kernel configuration, ALL.
I have made a few miscellaneous changes, too:
gem(4): use LIST_EMPTY(), LIST_FOREACH().
mtd(4): handle media ioctls, for a change!
axe(4): do not track link status in sc->axe_link any longer
nfe(4), aue(4), axe(4), udav(4), url(4): do not reset all PHYs
on a change of media
Except for the change to mtd(4), no functional changes are intended.
XXX This patch affects more architectures than I can feasibly
XXX compile and run. I have compiled macppc, sparc64, i386. I
XXX have run the patches on i386 boxen with bnx(4) and sip(4).
XXX Compiling and running on evbmips (MERAKI, ADM5120) is in
XXX progress.
the same struct work before workqueue(9) has internally started to work on
the task.
So to make sure that doesn't happen, provide a semaphore not to run the
workqueue multiple times. It might be clearer just skip using workqueue(9)
and use a thread for about everything, but oh well, I leave that to
someone else.
Now is@ can yank his USB-to-Ethernet adapter while the interface is up.
Support non-blocking reads from USB printers. With this, escputil can
query the printer model, and I can print a test page with gutenprint
5.1 and cups. Add many comments explaining why the support is not
quite right. (This change is quite a bit less invasive than a
"correct" fix, and thus more reasonable to pull up to netbsd-4.)
Rototill debugging, so that all DPRINTFN have a level, and so that the
message is printed if the debug level is >= the number in the source
code. Document debug level plan.
Fix bug where only one status change would be printed (by inspection,
not tested).
Document scheme for reading/discarding data when ulpt(4) is opened for
write only.
Delete dead code.
Plan and patch posted on tech-kern without objections.
Add if_set_sadl() that both sets the link-layer address length and
replaces the current link-layer address with a new one, and use it
throughout the tree.
