for removal are:
- No code in tree uses this possibility.
- The documentation ifmib(4) doesn't say that such possibility
exist. The example provided in manual page only reads data.
- On many interfaces the feature simply doesn't work, since they
do accounting in hardware, and overwrite if_data on tick.

optional attributes field.
- Add a 'machdep.smap' sysctl that exports the SMAP table of the running
system as an array of the ACPI 3.0 structure. (On older systems, the
attributes are given a value of zero.) Note that the sysctl only
exports the SMAP table if it is available via the metadata passed from
the loader to the kernel. If an SMAP is not available, an empty array
is returned.
- Add a format handler for the ACPI 3.0 SMAP structure to the sysctl(8)
binary to format the SMAP structures in a readable format similar to
the format found in boot messages.

Prior to this change we triggered ARC reclaim when kmem usage passed 3/4
of the total available, as indicated by vmem_size(kmem_arena, VMEM_ALLOC).
This could lead large amounts of unused RAM e.g. on a 192GB machine with
ARC the only major RAM consumer, 40GB of RAM would remain unused.
The old method has also been seen to result in extreme RAM usage under
certain loads, causing poor performance and stalls.
We now trigger ARC reclaim when the number of free pages drops below the
value defined by the new sysctl vfs.zfs.arc_free_target, which defaults
to the value of vm.v_free_target.

but has some retries.
Without this, single frame transmission in AMPDU will always look like
it succeeded fine, and thus AMRR will think it's totally fine to just
keep upping the rate upwards.
Now, this is still not quite right! For multi-frame aggregates the
completion happens in two parts - the TX done and the BA received.
The driver is currently double accounting those a little - there's no
way to say to the rate control code "I completed X frames, Y worked fine,
there were Z retries." And it's a bit odd with iwn, as the firmware
retransmits frames for us so we don't get to see how many retransmits
happened; only that it took longer than normal. I may have to extend
the rate control API to properly track that.
So this may keep the rate lower than it should be, but that's better
than keeping it higher than it should be.
Tested:
* 5100, STA mode
in preparation for the 5300 3x3 NIC.
During this particular adventure, I did indeed discover that a whole
swath of things made little to no sense.
Those included, and are fixed here:
* A lot of the antenna configuration bits assume the NIC has two receive
chains. That's blatantly untrue for NICs that don't.
* There was some disconnect between the antenna configuration when
forming a PLCP rate DWORD (which includes the transmit antenna
configuration), separate to the link quality antenna configuration.
So now there's helper functions to return which antenna configurations
to use and those are used wherever an antenna config is required.
* The 5300 does up to three stream TX/RX (so MCS0->23), however
the link quality table has only 16 slots. This means all of the
rate entries are .. well, dual-stream rates. If this is the case,
the "last MIMO" parameter can't be 16 or it panics the firmware.
Set it to 15.
* .. and since yes it has 16 slots, it only would try retransmitting
from MCS8->MCS23, which can be quite .. terrible. Hard-code the last
two retry slots to be the lowest configured rate.
* I noticed some transmit configuration command stuff is different
based on firmware API version, so I lifted that code from Linux.
* Add / augment some more logging to make it easier to capture this
stuff.
Now, 3x3 is still terrible because the link quality configuration is
plainly not good enough. I'll have to think about that.
However, the original goal of this - 3x3 operation on the Intel
5300 NIC - actually worked.
There are also rate control bugs in the way this driver handles
notifying the net80211 rate control code when AMPDU is enabled.
It always steps the rate up to the maximum rate possible - and
this eventually ends in much sadness. I'll fix that later.
As a side note - 2GHz HT40 now works on all the NICs I have tested.
As a second side note - this exposed some bad 3x3 behaviour in
the ath(4) rate control code where it starts off at a 3-stream rate
and doesn't downgrade quickly enough. This makes the initial
dhcp exchange take a long time. I'll fix the ath(4) rate code
to start at a low fixed 1x1 MCS rate and step up if everything
works out.
