As it turns out, the density code for DAT-160 (0x48) is the same
as for SDLT220. Since the SDLT values are already in the table,
we will leave them in place.
Thanks to Harald Schmalzbauer for confirming the DAT-72 density code.
lib/libmt/mtlib.c:
Add DAT-72 density code, and commented out DAT-160 density
code. Explain why DAT-160 is commented out. Add notes
explaining where the bpi values for these formats came from.
usr.bin/mt/mt.1:
Add DAT-72 density code, and add a note explaining that
the SDLTTapeI(110) density code (0x48) is the same as
DAT-160.

This allows a separate process to monitor when and how
syslogd exits. That process can then restart syslogd if needed.

simulators. In these cases we don't get an interrupt so will need to
schedule the task to write more data to the uart.

This new function can be used by other drivers to reserve the use of GPIO
pins.
Anyway, the use of ofw_gpiobus_parse_gpios() is preferred when possible.

- fix warning about comparison of 'uint8_t v_tpr >= 0' always being true.
- fix error triggered by an empty clobber list in the inline assembly for
"clgi" and "stgi"
- fix error when compiling "vmload %rax", "vmrun %rax" and "vmsave %rax". The
gcc assembler does not like the explicit operand "%rax" while the clang
assembler requires specifying the operand "%rax". Fix this by encoding the
instructions using the ".byte" directive.

ktr needs an overhaul to really only compile in the ones you want,
we've long passed the 31 bits it provides..

if_vmove().
In if_vmove(), if_detach_internal() and if_attach_internal() were
called in series to detach and reattach the interface. When
detaching, if_delgroup() was called and the interface leaves all of
the group membership. And then upon attachment, if_addgroup(ifp,
IFG_ALL) was called and it joined only "all" group again.
This had a problem. Normally, a cloned interface automatically joins
a group whose name is ifc_name of the cloner in addition to "all"
upon creation. However, if_vmove() removed the membership and did
not restore upon attachment.

SCSI-2 devices.
Some older tape devices claim to be SCSI-2, but actually do support
long position information. (Long position information includes
the current file mark.) For example, the COMPAQ SuperDLT1.
So we now only disable the check on SCSI-1 and older devices.
sys/cam/scsi/scsi_sa.c:
In saregister(), only disable fetching long position
information on SCSI-1 and older drives. Update the
comment to explain why.

draft-ietf-6man-enhanced-dad-13.
This basically adds a random nonce option (RFC 3971) to NS messages
for DAD probe to detect a looped back packet. This looped back packet
prevented DAD on some pseudo-interfaces which aggregates multiple L2 links
such as lagg(4).
The length of the nonce is set to 6 bytes. This algorithm can be disabled by
setting net.inet6.ip6.dad_enhanced sysctl to 0 in a per-vnet basis.

This is a QCA9558 SoC (2ghz 3x3) with an atheros 11ac PCIe 5GHz 3x3
NIC and an AR8327 gigabit ethernet switch.
TODO:
* The AR8327 gigabit switch support bugfixes are forthcoming.
* 11ac support and 11ac NIC support
This is enough to bring up the basic SoC support.
What works thus far:
* The mips74k core, pll setup, and UART (or else well, stuff would
be really difficult..)
* both USB 2.0 EHCI controllers
* on-board 2GHz 3x3 wifi (the other variant has 2GHz/5GHz wifi on-chip);
* arge0 - not yet sure why arge1 isn't firing off interrupts and thus
handling traffic, but I will soon figure it out and fix it here.
Tested:
* AP135 reference design, QCA9558 SoC, pretending to be an 11n
2GHz AP.
TODO:
* There's an interrupt mux hooking up devices to IP2 and IP3 - but it's
not a read-and-clear or write-to-clear register. So, trying to use it
naively like I have been ends up with massive interrupt storms.
For now the things that share those interrupts can just take them as
shared interrupts and try to play nice.
* There's two PCIe root complexes /and/ one of them can actually be
a PCIe device endpoint. Yes, you heard right. I have to teach the
AR724x PCIe bridge code to handle multiple instances with multiple
memory/irq regions, and then there'll be RC support, but EP support
isn't on my TODO list.
* I'm not sure why arge1 isn't up and running. I'll go figure that
out soon and fix it here.
Thankyou to Qualcomm Atheros for providing me with hardware and
an abundance of documentation about these things.
the CPU nexus.
* Add ahb as a possible bus attachment
* Lay a comment down to remind me or whoever else ends up trying
to debug why the EEPROM isn't mapped in as to what's going on.
There's two EHCI controllers in the QCA955x SoCs - they have different
interrupts available via various demux registers, but they both tie to
IP3.
So for now, allow them to be sharable so they can hang off of IP3.
