Run if_ndis.c:ndis_tick() via taskqueue_schedule(). Also run

Using these tweaks, I can now get the Broadcom BCM5701 NDIS
driver to load and run. Unfortunately, the version I have seems
to suffer from the same bug as the SMC 83820 driver, which is
that it creates a spinlock during its DriverEntry() routine.
I'm still debating the right way to deal with this.
frame, not the first. It is probably also not safe to free the mbuf chain
as soon as the OWN bit is cleared on the first descriptor since the chip
may not be done copying the frame into the transmit FIFO. Revert the part of
of busdma conversion (if_dc.c rev 1.115) which changed dc_txeof() to look for
the status in the first descriptor and free the mbuf chain when processing
the first descriptor for the frame, and revert the matching changes elsewhere
in the driver. This part of the busdma change caused the driver to report
spurious collisions and output errors, even when running in full-duplex mode.
Reverting the mbuf chain handling slightly complicates dc_dma_map_txbuf(),
since it is responsible for setting the OWN bits on the descriptors, but does
not normally have direct access to the mbuf chain.

the RT_MESSAGETABLE resources that some driver binaries have.
This allows us to print error messages in ndis_syslog().
- Correct the implementation of InterlockedIncrement() and
InterlockedDecrement() -- they return uint32_t, not void.
- Correct the declarations of the 64-bit arithmetic shift
routines in subr_ntoskrnl.c (_allshr, allshl, etc...). These
do not follow the _stdcall convention: instead, they appear
to be __attribute__((regparm(3)).
- Change the implementation of KeInitializeSpinLock(). There is
no complementary KeFreeSpinLock() function, so creating a new
mutex on each call to KeInitializeSpinLock() leaks resources
when a driver is unloaded. For now, KeInitializeSpinLock()
returns a handle to the ntoskrnl interlock mutex.
- Use a driver's MiniportDisableInterrupt() and MiniportEnableInterrupt()
routines if they exist. I'm not sure if I'm doing this right
yet, but at the very least this shouldn't break any currently
working drivers, and it makes the Intel PRO/1000 driver work.
- In ndis_register_intr(), save some state that might be needed
later, and save a pointer to the driver's interrupt structure
in the ndis_miniport_block.
- Save a pointer to the driver image for use by ndis_syslog()
when it calls pe_get_message().

and MiniportHandleInterrupt() is fired off later via a task queue in
ndis_intrtask(). This more accurately follows the NDIS interrupt handling
model, where the ISR does a minimal amount of work in interrupt context
and the handler is defered and run at a lower priority.
Create a separate ndis_intrmtx mutex just for the guarding the ISR.
Modify NdisSynchronizeWithInterrupt() to aquire the ndis_intrmtx
mutex before invoking the synchronized procedure. (The purpose of
this function is to provide mutual exclusion for code that shares
variables with the ISR.)
Modify NdisMRegisterInterrupt() to save a pointer to the miniport
block in the ndis_miniport_interrupt structure so that
NdisSynchronizeWithInterrupt() can grab it later and derive

Implement NdisMIndicateStatus() and NdisMIndicateStatusComplete()

NDIS 5.0 and later, they're just macros.
Allocate a few extra packets/buffers beyond what the driver asks

which were both horribly broken.

The SMC 9462 gigE driver (natsemi 83820-based copper)
incorrectly creates a spinlock in its DriverEntry()
routine and then destroys it in its MiniportHalt()
handler. This is wrong: spinlocks should be created
in MiniportInit(). In a Windows environment, this is
often not a problem because DriverEntry()/MiniportInit()
are called once when the system boots and MiniportHalt()
or the shutdown handler is called when the system halts.
With this stuff in place, this driver now seems to work:
ndis0: <SMC EZ Card 1000> port 0xe000-0xe0ff mem 0xda000000-0xda000fff irq 10 at device 9.0 on pci0
ndis0: assign PCI resources...
ndis_open_file("FLASH9.hex", 18446744073709551615)
ndis0: Ethernet address: 00:04:e2:0e:d3:f0
This should fix the problem with removing an address space handler
although we don't currently use that capability so it's unlikely anyone
saw this problem.

Add a -n flag to ndiscvt to allow the user to override the default
device name of NDIS devices. Instead of "ndis0, ndis1, etc..."
you can have "foo0, foo1, etc..." This allows you to have more than
one kind of NDIS device in the kernel at the same time.
Convert from printf() to device_printf() in if_ndis.c, kern_ndis.c

handler in kern_ndis.c.

method with something a little more intelligent: use BUS_GET_RESOURCE_LIST()
to run through all resources allocated to us and map them as needed. This
way we know exactly what resources need to be mapped and what their RIDs
are without having to guess. This simplifies both ndis_attach() and
ndis_convert_res(), and eliminates the unfriendly "ndisX: couldn't map
<foo>" messages that are sometimes emitted during driver load.
