When the CPU Topology was added to bhyve in r332298 the SMBIOS table was
missed, this table passes topology information to the system and was still
using the old concept of each vCPU is a socket with 1 core and 1 thread.
This code did not even try to use the old sysctl information to adjust
this data.
Correct that by building a proper SMBios table, mapping the > 254 cases to
0 per the SMBios 2.6 specification that is claimed by the structure.

By default, cores are now assigned to queues in a sequential
manner rather than all NICs starting at the first core. On a four-core
system with two NICs each using two queue pairs, the nic:queue -> core
mapping has changed from this:
0:0 -> 0, 0:1 -> 1
1:0 -> 0, 1:1 -> 1
To this:
0:0 -> 0, 0:1 -> 1
1:0 -> 2, 1:1 -> 3
Additionally, a device can now be configured to use separate cores for TX
and RX queues.
Two new tunables have been added, dev.X.Y.iflib.separate_txrx and
dev.X.Y.iflib.core_offset. If core_offset is set, the NIC is not part
of the auto-assigned sequence.

Drivers can now pass up numa domain information via the
mbuf numa domain field. This information is then used
by TCP syncache_socket() to associate that information
with the inpcb. The domain information is then fed back
into transmitted mbufs in ip{6}_output(). This mechanism
is nearly identical to what is done to track RSS hash values
in the inp_flowid.
Follow on changes will use this information for lacp egress
port selection, binding TCP pacers to the appropriate NUMA
domain, etc.

The disk_open() function searches for "the best partition" when slice and
partition information is not provided as part of the device name. As of
r345477 the slice and partition fields of a disk_devdesc are initialized to
D_SLICEWILD and D_PARTWILD; in the past they were initialized to -1, which
was sometimes interpreted as meaning 'wildcard' and sometimes as 'open the
raw partition' depending on the context. So as an unintended side effect of
r345477 it became basically impossible to ever open a disk or partition
without doing the 'best partition' search. One visible effect of that was
the inability to open the raw disk to read the partition table correctly in
zfs_probe_dev(), leading to failures to find the zfs pool unless it was on
the first partition.
Now instead of always initializing slice and partition to wildcards, the
disk_parsedev() function initializes them based on the presence of a
path/file name following the device. If there is any path or filename
following the ':' that ends the device name, then slice and partition are
initialized to D_SLICEWILD and D_PARTWILD. If there is nothing after the
':' then it is considered to be a request to open the raw device or
partition itself (not a file stored within it), and the fields are
initialized to D_SLICENONE and D_PARTNONE.
With this change in place, all the tests in src/tools/boot are succesful
again, including the recently-added cases of booting from a zfs pool on
a partition other than slice 1 of the device.

Previously, a pid check was used to prevent open of the tun(4); this works,
but may not make the most sense as we don't prevent the owner process from
opening the tun device multiple times.
The potential race described near tun_pid should not be an issue: if a
tun(4) is to be handed off, its fd has to have been sent via control message
or some other mechanism that duplicates the fd to the receiving process so
that it may set the pid. Otherwise, the pid gets cleared when the original
process closes it and you have no effective handoff mechanism.
Close up another potential issue with handing a tun(4) off by not clobbering
state if the closer isn't the controller anymore. If we want some state to
be cleared, we should do that a little more surgically.
Additionally, nothing prevents a dying tun(4) from being "reopened" in the
middle of tun_destroy as soon as the mutex is unlocked, quickly leading to a
bad time. Return EBUSY if we're marked for destruction, as well, and the
consumer will need to deal with it. The associated character device will be
destroyed in short order.

It seems that there should be a better way to handle this, but this seems to
be the more common approach and it should likely get replaced in all of the
places it happens... Basically, thread 1 is in the process of destroying the
tun/tap while thread 2 is executing one of the ioctls that requires the
tun/tap mutex and the mutex is destroyed before the ioctl handler can
acquire it.
This is only one of the races described/found in PR 233955.
