f5c30c4e8d Bring over some initial power save management support, reset path
fixes and beacon programming / debugging into the ath(4) driver.

The basic power save tracking:

* Add some new code to track the current desired powersave state; and
* Add some reference count tracking so we know when the NIC is awake; then
* Add code in all the points where we're about to touch the hardware and
  push it to force-wake.

Then, how things are moved into power save:

* Only move into network-sleep during a RUN->SLEEP transition;
* Force wake the hardware up everywhere that we're about to touch
  the hardware.

The net80211 stack takes care of doing RUN<->SLEEP<->(other) state
transitions so we don't have to do it in the driver.

Next, when to wake things up:

* In short - everywhere we touch the hardware.
* The hardware will take care of staying awake if things are queued
  in the transmit queue(s); it'll then transit down to sleep if
  there's nothing left.  This way we don't have to track the
  software / hardware transmit queue(s) and keep the hardware
  awake for those.

Then, some transmit path fixes that aren't related but useful:

* Force EAPOL frames to go out at the lowest rate.  This improves
  reliability during the encryption handshake after 802.11
  negotiation.

Next, some reset path fixes!

* Fix the overlap between reset and transmit pause so we don't
  transmit frames during a reset.
* Some noisy environments will end up taking a lot longer to reset
  than normal, so extend the reset period and drop the raise the
  reset interval to be more realistic and give the hardware some
  time to finish calibration.
* Skip calibration during the reset path.  Tsk!

Then, beacon fixes in station mode!

* Add a _lot_ more debugging in the station beacon reset path.
  This is all quite fluid right now.
* Modify the STA beacon programming code to try and take
  the TU gap between desired TSF and the target TU into
  account.  (Lifted from QCA.)

Tested:

* AR5210
* AR5211
* AR5212
* AR5413
* AR5416
* AR9280
* AR9285

TODO:

* More AP, IBSS, mesh, TDMA testing
* Thorough AR9380 and later testing!
* AR9160 and AR9287 testing

c6a0cc2e21 Some Linux guests will implement a 'halt' by disabling the APIC and executing
the 'HLT' instruction. This condition was detected by 'vm_handle_hlt()' and
converted into the SPINDOWN_CPU exitcode . The bhyve(8) process would exit
the vcpu thread in response to a SPINDOWN_CPU and when the last vcpu was
spun down it would reset the virtual machine via vm_suspend(VM_SUSPEND_RESET).

This functionality was broken in r263780 in a way that made it impossible
to kill the bhyve(8) process because it would loop forever in
vm_handle_suspend().

Unbreak this by removing the code to spindown vcpus. Thus a 'halt' from
a Linux guest will appear to be hung but this is consistent with the
behavior on bare metal. The guest can be rebooted by using the bhyvectl
options '--force-reset' or '--force-poweroff'.

a17937bdd0 For the VM_PHYSSEG_DENSE case, checking the requested range to fall
into the area backed by vm_page_array wrongly compared end with
vm_page_array_size.  It should be adjusted by first_page index to be
correct.

Also, the corner and incorrect case of the requested range extending
after the end of the vm_page_array was incorrectly handled by
allocating the segment.

Fix the comparision for the end of range and return EINVAL if the end
extends beyond vm_page_array.

68bbdd0e71 Fix "netstat -gW" behavior broken in r259638.
netstat has two options for printing multicast tables:
sysctl (the default one for live systems) and kvm-based one (for cores).
It looks like kvm-based one hasn't been working since it's been introduced
in r190012 due to absence of mfctablesize kernel symbol.
Check for all ipv4-multicast symbols being correctly resolved was introduced
in r259638 regardless of 'live' value leading to "No IPv4 MROUTING" error
message.

7278b62aee Fix a panic when removing an IP address from an interface, if the same address
exists on another interface.  The panic was introduced by change 264887, which
changed the fibnum parameter in the call to rtalloc1_fib() in
ifa_switch_loopback_route() from RT_DEFAULT_FIB to RT_ALL_FIBS.  The solution
is to use the interface fib in that call.  For the majority of users, that will
be equivalent to the legacy behavior.

f0fdcfe247 Allow a virtual machine to be forcibly reset or powered off. This is done
by adding an argument to the VM_SUSPEND ioctl that specifies how the virtual
machine should be suspended, viz. VM_SUSPEND_RESET or VM_SUSPEND_POWEROFF.

The disposition of VM_SUSPEND is also made available to the exit handler
via the 'u.suspended' member of 'struct vm_exit'.

This capability is exposed via the '--force-reset' and '--force-poweroff'
arguments to /usr/sbin/bhyvectl.
