9494715d4b Reset the NIC if ANI is enabled or disabled.
Although this may not be what the original sysctl was designed to do,
it feels a bit more "expected".

Before, if ANI is disabled, the initial ANI parameters are still written
to the hardware, even if they're not enabled. "ANI enabled" would then
adjust the noise immunity parameters dynamically. Disabling ANI would
simply leave the existing noise immunity parameters where they are,
and disable the dynamic part.

The problem is that disabling ANI doesn't leave the hardware in
a consistent, predictable state - so asking a user to disable ANI
wouldn't actually reset the NIC to a consistent set of PHY signal
detection parameters, resulting in an unpredictable/unreliable outcome.
This makes it difficult to get reliable debugging information from
the user.

dc4300d605 Make ums(4) driver more picky, not attaching to "mouses" with absolute
coordinates, such as digitizers and touch-screens, leaving these devices
to uhid(4) and user-level. Specially patched xf86-input-mouse driver can
handle them, that isn't done and can't be done properly with ums(4)
because of mouse(4) protocol limitations.

b55bc3f9ac In some cases, at least on Marvell 88SE912x controllers, Current Command
Slot field of the PxCMD register may point to an empty command slot.
That breaks command timeout detection logic, making impossible to find
what command actually caused timeout, and leading to infinite wait.
Workaround that by checking whether pointed command slot is really used
and can timeout in its time. And if not, fallback to the dumb algorithm
used with FBS -- let all commands to time out and then fail all of them.

6afa7d74ec Add control for ATA disk read-ahead, alike to the previously added write
cache control. Some controller BIOS'es tend to disable read-ahead, that

56747017c9 In some cases failed SATA disks may report their presence, but don't
respond to any commands. I've found that because of multiple command
retries, each of which cause 30s timeout, bus reset and another retry or
requeue for many commands, it may take ages to eventually drop the
failed device. The odd thing is that those retries continue even after
XPT considered device as dead and invalidated it.

This patch makes cam_periph_error() to block any command retries after
periph was marked as invalid. With that patch all activity completes in
1-2 minutes, just after several timeouts, required to consider device
death. This should make ZFS, gmirror, graid, etc. operation more robust.

6f368c5da4 - Send the RELSIM_ADJUST_OPENINGS in response to a MPI_EVENT_QUEUE_FULL using
the right SIM in case the HBA is RAID-capable but the target in question is
  not a hot spare or member of a RAID volume.
- Report the loss and addition of SAS and SATA targets detected via PHY link
  status changes and signalled by MPI_EVENT_SAS_DEVICE_STATUS_CHANGE to cam(4)
  as lost devices and trigger rescans as appropriate. Without this it can take
  quite some time until a lost device actually is no longer tried to be used,
  if it ever stops. [1]
- Handle MPI_EVENT_IR2, MPI_EVENT_LOG_ENTRY_ADDED, MPI_EVENT_SAS_DISCOVERY
  and MPI_EVENT_SAS_PHY_LINK_STATUS silently as these serve no additional
  purpose beyond adding cryptic entries to logs.

Thanks to Hans-Joerg Sirtl for providing one of the HBAs these changes were
developed with and RIP to the mainboard that didn't survive testing them.

50b05401d3 remove RESTARTABLE_PANICS option
This is done per request/suggestion from John Baldwin
who introduced the option.  Trying to resume normal
system operation after a panic is very unpredictable
and dangerous.  It will become even more dangerous
when we allow a thread in panic(9) to penetrate all
lock contexts.
I understand that the only purpose of this option was
for testing scenarios potentially resulting in panic.

64e0ba1afe This update changes the mnt_flag field in the mount structure from
32 bits to 64 bits and eliminates the unused mnt_xflag field.  The
existing mnt_flag field is completely out of bits, so this update
gives us room to expand. Note that the f_flags field in the statfs
structure is already 64 bits, so the expanded mnt_flag field can
be exported without having to make any changes in the statfs structure.

d54d0f83bc Modify the radar API a little to be easier to "change" via run-time
tools.

* introduce pe_enabled, which (will) indicate whether the radar
  detection stuff is enabled or not. Right now it's incorrectly
  set, based on something previously written. I'll sort it out
  later.

* Don't set HAL_PHYERR_PARAM_ENABLE in pe_relstep to say whether
  radar detection is on.

* Return whether blockradar, fir128 and enmaxrssi is enabled.

* Change some of the phyerr params to be integers rather than
  HAL_BOOL so they can be set to the NOPARAM value when the
  setup function is called. This is in line with other radar
  parameters.

* Add new configuration parameters for fir128, blockradar and
  enmaxrssi, rather than defaulting to off, on and on respectively.
