- make usb2_power_mask_t 16-bit
- remove "usb2_config_sub" structure from "usb2_config". To compensate for this
"usb2_config" has a new field called "usb_mode" which select for which mode
the current xfer entry is active. Options are: a) Device mode only b) Host
mode only (default-by-zero) c) Both modes. This change was scripted using
the following sed script: "s/\.mh\././g".
- the standard packet size table in "usb_transfer.c" is now a function, hence
the code for the function uses less memory than the table itself.

or URB_FUNCTION_CLASS_xxx with HAL preemption lock that means it's
non-sleepable during USB requests though usb2_do_request() requires a
sleep so it needs to send queries to the default pipe without those
interfaces to avoid sleep.
whatever the IRP flag is because some drivers (eg. RTL8187L NDIS driver)
call IoCompleteRequest() without setting flags. It will prevent waiting
a event forever at attach.
Based on the HAL preemption lock there is a problem on SMP machines
and causes a panic.
o When a device detached the current tactic to detach NDIS USB driver is
to call SURPRISE_REMOVED event. So it don't need to call
ndis_halt_nic() again. This fixes some page faults when some drivers
work abnormal.
o it assumes now that URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER is in
DISPATCH_LEVEL (non-sleepable) and as further work
URB_FUNCTION_VENDOR_XXX and URB_FUNCTION_CLASS_XXX should be.

Now the NDISulator supports NDIS USB drivers that it've tested with
devices as follows:
- Anygate XM-142 (Conexant)
- Netgear WG111v2 (Realtek)
- U-Khan UW-2054u (Marvell)
- Shuttle XPC Accessory PN20 (Realtek)
- ipTIME G054U2 (Ralink)
- UNiCORN WL-54G (ZyDAS)
- ZyXEL G-200v2 (ZyDAS)
All of them succeeded to attach and worked though there are still some
problems that it's expected to be solved.
To use NDIS USB support, you should rebuild and install ndiscvt(8) and
if you encounter a problem to attach please set `hw.ndisusb.halt' to
0 then retry.
I expect no changes of the NDIS code for PCI, PCMCIA devices.

return NDIS_STATUS_PENDING. In this case, it's waiting for 5 secs to
get the response from drivers now. However, some NDIS drivers can send
the response before NDIS framework gets ready to receive it so we might
always be blocked for 5 secs in current implementation. NDIS framework
should reset the event before calling NDIS driver's callback not after.

exit before ndis gets around to sleep so it will be stuck indefinitely. This
change reuses the kq_exit variable to indicate that the thread has gone and

exited then it will not sleep at all.

file objects calling a user-specified predicate function on each object.
The iteration terminates either when the entire list has been iterated
over or the predicate function returns a non-zero value.
linker_file_foreach() returns the value returned by the last invocation
of the predicate function. It also accepts a void * context pointer that
is passed to the predicate function as well. Using an iterator function
avoids exposing linker internals to the rest of the kernel making locking
simpler.

for a Windows ISR is 'BOOLEAN isrfunc(KINTERRUPT *, void *)' meaning
the ISR get a pointer to the interrupt object and a context pointer,
and returns TRUE if the ISR determines the interrupt was really generated
by the associated device, or FALSE if not.
I had mistakenly used 'void isrfunc(void *)' instead. It happens the
only thing this affects is the internal ndis_intr() ISR in subr_ndis.c,
but it should be fixed just in case we ever need to register a real
Windows ISR vi IoConnectInterrupt().
For NDIS miniports that provide a MiniportISR() method, the 'is_our_intr'
value returned by the method serves as the return value from ndis_isr(),
and 'call_isr' is used to decide whether or not to schedule the interrupt
handler via DPC. For drivers that only supply MiniportEnableInterrupt()
and MiniportDisableInterrupt() methods, call_isr is always TRUE and
is_our_intr is always FALSE.
In the end, there should be no functional changes, except that now
ntoskrnl_intr() can terminate early once it finds the ISR that wants
to service the interrupt.

Intel's web site requires some minor tweaks to get it to work:
- The driver seems to have been released with full WMI tracing enabled,
and makes references to some WMI APIs, namely IoWMIRegistrationControl(),
WmiQueryTraceInformation() and WmiTraceMessage(). Only the first
one is ever called (during intialization). These have been implemented
as do-nothing stubs for now. Also added a definition for STATUS_NOT_FOUND
to ntoskrnl_var.h, which is used as a return code for one of the WMI
routines.
- The driver references KeRaiseIrqlToDpcLevel() and KeLowerIrql()
(the latter as a function, which is unusual because normally
KeLowerIrql() is a macro in the Windows DDK that calls KfLowewIrql()).
I'm not sure why these are being called since they're not really
part of WDM. Presumeably they're being used for backwards
compatibility with old versions of Windows. These have been
implemented in subr_hal.c. (Note that they're _stdcall routines
instead of _fastcall.)
- When querying the OID_802_11_BSSID_LIST OID to get a BSSID list,
you don't know ahead of time how many networks the NIC has found
during scanning, so you're allowed to pass 0 as the list length.
This should cause the driver to return an 'insufficient resources'
error and set the length to indicate how many bytes are actually
needed. However for some reason, the Intel driver does not honor
this convention: if you give it a length of 0, it returns some
other error and doesn't tell you how much space is really needed.
To get around this, if using a length of 0 yields anything besides
the expected error case, we arbitrarily assume a length of 64K.
This is similar to the hack that wpa_supplicant uses when doing
a BSSID list query.
