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.
to remove the frobbing that drivers must do in the hci_unit structure.
- driver provides a static const interface descriptor
- hci_unit is allocated by hci_attach() rather than part of softc
- statistics are compiled by driver and provided on request
- driver provides output methods and is responsible for output queue
- stack provides input methods and is responsible for input queue
- mutex is used to arbitrate device queue access
+ make sure ni->ni_txrate is always initialized to a meaningful value by
redefining ic->ic_newassoc.
this should prevent "bogus xmit rate" panics when operating in HostAP
mode.
+ s/RT2573_[TR]X_LIST_COUNT/RUM_[TR]X_LIST_COUNT/
+ Restore the workaround for rate==0 bug.

We need to sanity check the DeviceClass in this case.
Currently known guilty products:
0x050d/0x0121 Belkin Bluetooth and USB2LAN
If this turns out to be more common, we could use a quirk table.
make bluetooth stack keep device_t instead of softc pointer as
device is not necessarily part of softc, and pass device_t to
driver callbacks. hci_devname is no longer required.
error = (cmd == SIOCADDMULTI) ?
ether_addmulti(ifr, &sc->sc_ec) :
ether_delmulti(ifr, &sc->sc_ec);
if (error == ENETRESET) {
to this,
if ((error = ether_ioctl(ifp, cmd, data)) == ENETRESET) {
which does the same thing.
(A bazillion is a very large number. This seems to make the i386
ALL kernel smaller by 3kB to 4kB.)
Use ifreq_getaddr() twice in es(4).
Whitespace nits.
identify sockaddr_dl abuse that remains in the kernel, especially
the potential for overwriting memory past the end of a sockaddr_dl
with, e.g., memcpy(LLADDR(), ...).
-> the current names are confusing (didn't change other drivers)
* fix invalid memory access in usbd_transfer (kern/24636)
-> needed for this driver
* fix USB HC detach race condition (kern/32011)
-> main patch needed for this driver, sc_dying changes in other drivers
not necessary but seem right to me

WQ_PERCPU flag for workqueue and additional argument for workqueue_enqueue()
to assign a CPU might be used. Notes:
- For now, the list is used for workqueue_queue, which is non-optimal,
and will be changed with array, where index would be CPU ID.
- The data structures should be changed to be cache-friendly.

USB problems - just return in detach if the softc appears not to be
filled in completely.
(This is a common problem with usb and probably other drivers which
support detach; we need some API support to deal with this cleanly.)
