(most recently bde), so I'll commit the module I've had knocking
around in my tree for a while. This may have some rough edges, so if
you are able to build it on non-i386 platform (including pc98) please
let me know you succeeded. When I get enough reports, I'll connect it
to the build. If there are problems, feel free to fix them.

sched_cpu() locks an sx lock (allproc_lock) which can sleep if it fails to
acquire the lock, it is not safe to execute this in a callout handler from
softclock().
For received packets, an status of NDIS_STATUS_RESOURCES means we need
to copy the packet data and return the ndis_packet to the driver immediatel.
NDIS_STATUS_SUCCESS means we get to hold onto the packet, but we have
to set the status to NDIS_STATUS_PENDING so the driver knows we're
going to hang onto it for a while.
For transmit packets, NDIS_STATUS_PENDING means the driver will
asynchronously return the packet to us via the ndis_txeof() routine,
and NDIS_STATUS_SUCCESS means the driver sent the frame, and NDIS
(i.e. the OS) retains ownership of the packet and can free it
right away.
evaluate them. Whatever they're meant to do, they're doing it wrong.
Also:
- Clean up last bits of NULL fallout in subr_pe
- Don't let ndis_ifmedia_sts() do anything if the IFF_UP flag isn't set
- Implement NdisSystemProcessorCount() and NdisQueryMapRegisterCount().
packet being freed has NDIS_STATUS_PENDING in the status field of
the OOB data. Finish implementing the "alternative" packet-releasing
function so it doesn't crash.
For those that are curious about ndis0: <ORiNOCO 802.11abg ComboCard Gold>:
1123 packets transmitted, 1120 packets received, 0% packet loss
round-trip min/avg/max/stddev = 3.837/6.146/13.919/1.925 ms
Not bad!
add one if the SYN flag was set in the original packet. This seems to make
ip6fw reset work correctly for new and in-progress connections. Update
the man page to reflect the fact it now seems to work.

MFC after: 2 weeks
this driver by introducing a flag saying we already stopped the device.
On my Soekris net4801, this took a ping -i 0.001 from spending 80% of
time in interrupt handling to 10% (approx numbers).
This was a particular problem for the net4801 because the tree
interfaces share the same interrupt, but it would be a problem for
any configuration where an unused if_sis interface shares an interrupt
with a busy device.
Other drivers may have similar problems.

The log message for rev.1.160 of kern/uipc_syscalls.c and associated
changes only claimed to add restrict qualifiers (which have no effect in
the kernel so they probably shouldn't be added), but the following
interface changes were also made:
- caddr_t to `void *' and `struct sockaddr_t *'
- `int *' to `socklen_t *'.
These interface changes are not quite null, and this fix is quick (like
the changes in uipc_syscalls 1.160) because it uses bogus casts instead
of complete bounds-checked conversions.
Things should be fixed better when the conversions can be done without
using the stack gap. linux_check_hdrincl() already uses the stack gap
and is fixed completely though the type mismatches in it were not fatal
(there were only fatal type mismatches from unopaquing pointers to
[o]sockaddr't's -- the difference between accept()'s args and oaccept()'s
args is now non-opaque, but this is not reflected in their args structs).
flag isn't set.
- In ndis_attach(), halt the NIC before exiting the routine. Calling
ndis_init() will bring it up again, and we don't want it running
(and potentially generating interrupts) until we're ready to deal
with it.
mbuf<->packet housekeeping. Instead, add a couple of extra fields
to the end of ndis_packet. These should be invisible to the Windows
driver module.
This also lets me get rid of a little bit of evil from ndis_ptom()
(frobbing of the ext_buf field instead of relying on the MEXTADD()
macro).
- Fix ndis_time().
- Implement NdisGetSystemUpTime().
- Implement RtlCopyUnicodeString() and RtlUnicodeStringToAnsiString().
- In ndis_getstate_80211(), use sc->ndis_link to determine connect
status.

- Add explicit cardbus attachment in if_ndis.c
- Clean up after moving bus_setup_intr() in ndis_attach().
- When setting an ssid, program an empty ssid as a 1-byte string
with a single 0 byte. The Microsoft documentation says this is
how you're supposed to tell the NIC to attach to 'any' ssid.
- Keep trace of callout handles for timers externally from the
ndis_miniport_timer structs, and run through and clobber them
all after invoking the haltfunc just in case the driver left one
running. (We need to make sure all timers are cancelled on driver
unload.)
- Handle the 'cancelled' argument in ndis_cancel_timer() correctly.
