This should fix a panic recently reported on -current occuring when taking

triggers bfe_stop(), which also destroys all TX/RX descriptor dmamaps. Hence
the subsequent "ifconfig bfe0 up" would force the device to use those

resources. When allocating 6 ports for a 4 port range isa code
returns an error. I'm not sure yet why this is the case, but suspect
it is just a non-regularity in how the resource allocation code works
which should be corrected. Use 1 as the ports size in this case.
However, in the hints case, we have to specify the length, so use 6 in
that case. I believe that this is also acpi friendly.
Also, complain when we can't allocate FDOUT register space. Right now we

When there's no resource for FDCTL, go ahead and allocate one by hand.
Many PNPBIOS tables don't list this resource, and our hints mechanism also
doesn't cover that range. If we can't allocate it, whine, but fake up

at some point result in a status event being triggered (it should
be a link down event: the Microsoft driver design guide says you
should generate one when the NIC is initialized). Some drivers
generate the event during MiniportInitialize(), such that by the
time MiniportInitialize() completes, the NIC is ready to go. But
some drivers, in particular the ones for Atheros wireless NICs,
don't generate the event until after a device interrupt occurs
at some point after MiniportInitialize() has completed.
The gotcha is that you have to wait until the link status event
occurs one way or the other before you try to fiddle with any
settings (ssid, channel, etc...). For the drivers that set the
event sycnhronously this isn't a problem, but for the others
we have to pause after calling ndis_init_nic() and wait for the event
to arrive before continuing. Failing to wait can cause big trouble:
on my SMP system, calling ndis_setstate_80211() after ndis_init_nic()
completes, but _before_ the link event arrives, will lock up or
reset the system.
What we do now is check to see if a link event arrived while
ndis_init_nic() was running, and if it didn't we msleep() until
it does.
Along the way, I discovered a few other problems:
- Defered procedure calls run at PASSIVE_LEVEL, not DISPATCH_LEVEL.
ntoskrnl_run_dpc() has been fixed accordingly. (I read the documentation
wrong.)
- Similarly, the NDIS interrupt handler, which is essentially a
DPC, also doesn't need to run at DISPATCH_LEVEL. ndis_intrtask()
has been fixed accordingly.
- MiniportQueryInformation() and MiniportSetInformation() run at
DISPATCH_LEVEL, and each request must complete before another
can be submitted. ndis_get_info() and ndis_set_info() have been
fixed accordingly.
- Turned the sleep lock that guards the NDIS thread job list into
a spin lock. We never do anything with this lock held except manage
the job list (no other locks are held), so it's safe to do this,
and it's possible that ndis_sched() and ndis_unsched() can be
called from DISPATCH_LEVEL, so using a sleep lock here is
semantically incorrect. Also updated subr_witness.c to add the
lock to the order list.
Change fhc(4) to use IRQ numbers instead of RIDs for allocating the
IRQs of children. This works similar to e.g. sbus(4), i.e. add the
IRQ resources as fully specified to the resource lists of the children,
allocate them like normal. When establishing the interrupt search the
interrupt maps of the children for a matching INO to determine which
map we need to write the fully specified interrupt number to and to
enable the mapping (before the RID was used to indicate which interrupt
map to use).

This pointed out that we were doing the wrong thing when we failed to

driver is loaded, we can go w/o having to allocate them. We use
pci_cfg_save/restore to restore the BARs with these resources.
