* Factor out queue selection (epair_select_queue()) and mbuf
preparation (epair_prepare_mbuf()) from epair_menq(). It simplifies
epair_menq() implementation and reduces the amount of dependencies
on the neighbouring epair.
* Use dedicated epair_set_state() instead of 2-lines copy-paste
* Factor out unit selection code (epair_handle_unit()) from
epair_clone_create(). It simplifies the clone creation logic.

Summary:
Move SIOCAIFADDR_IN6 (current "primary" ioctl to add an IPv6
interface address) handling code to the dedicated in6_addifaddr()
function and make it a part of KPI. This allows in-kernel users to
add/delete interfaces addresses without relying on ioctl interface.

Rework the pmap_bootstrap table generation so we can use it with
partially filled out page tables after the DMAP has been bootstrapped.
This allows it to be reused by the later bootstrap code.

* change current NTP services offered by the FreeBSD Installer;
* no longer offer ntpdate to be enabled and started on boot;
* start offering the option to make ntpd set the date and time on boot itself.
The motivation for this change comes from the ntpdate(8) manpage:
Note: The functionality of this program is now available in the ntpd(8)
program. See the -q command line option in the ntpd(8) page. After a
suitable period of mourning, the ntpdate utility is to be retired from
this distribution.

Sysctl OIDs were internally stored in linked lists, triggering O(n^2)
behavior when userland iterates over many of them. The slowdown is
noticeable for MIBs that have > 100 children (for example, vm.uma). But
it's unignorable for kstat.zfs when a pool has > 1000 datasets.
Convert the linked lists into RB trees. This produces a ~25x speedup
for listing kstat.zfs with 4100 datasets, and no measurable penalty for
small dataset counts.
Bump __FreeBSD_version for the KPI change.

This is mostly cosmetic, but it also doesn't leave a gap of time where
no structures are valid. Instead, we permit the ISR to continue to
use the previous structure if the write to update cal_current isn't

This uses fixed-point math already used elsewhere in the kernel for
sub-second time values. To avoid overflows this does require updating
the calibration once a second rather than once every 30 seconds. Note
that the cxgbe driver already queries multiple registers once a second
for the statistics timers. This version also uses fewer instructions
with no branches (for the math portion) in the per-packet fast path.

While we could add the dummy includes directory manually to only the
drivers needing it, it seems a lot easier to simply add it to all

This is needed for more drivers (and to remove some #ifdef in current

While for in-kernel we already have LINUXKPI_INCLUDES in kern.pre.mk
for kmod builds we've not had a common define to use leading to various

In order for the include list to be expanded more easily in the future,
e.g., adding the "dummy" includes (for all) and to harmonize code,
duplicate LINUXKPI_INCLUDES to kmod.mk and use it for all module Makefiles.

Translating the provided range prior to rman_reserve_resource(9) is
decidedly wrong; the caller may be trying to do a wildcard allocation,
for which the implementation is expected to DTRT and clamp the range to
what's actually feasible.
We don't use the resulting translation here anyways, so just remove it
entirely -- the rman in the default implementation is derived from
sc->ranges, so the translation should trivially succeed every time as
long as the reservation succeeded. If something has gone awry in a
derived driver, we'll detect it when we translate prior to activation,
so there's likely no diagnostic value in retaining the translation after
reservation either.

The ending of a connection can tell us a lot about what happened i.e. did
it fail to setup, did it timeout, was it a normal close. Often times this is
useful information to help analyze and debug issues. Rack has had
end status for some time but the base stack as not. Lets go a ahead
and add in the missing bits to populate the end status.

Right now if you use rack with cubic (the new default cc) you will have
improper results. This is because rack uses different variables than
the base stack (or bbr) and thus tcp_compute_pipe() always returns
so that cubic will choose a 30% backoff not the 50% backoff it should
when it is newreno compatibility mode. The fix is to allow a stack (rack)
to override its own compute_pipe.

When the tunneled (IPv6) traffic had traffic class bits set (but only >=

This happened because the address family check in ovpn_get_af() failed

the packet.
While here also extend the existing 6-in-6 test case to trigger this

iwlwifi can return early from probe (in FreeBSD attach) while a separate
thread is still grinding loading the firmware and setting things up.
For us this means that kldload succeeded but we may not have a physical
wireless interface (com) yet but the rc framework might already try to
configure a vap on one.
Wait until we get a firmware completion event from the other thread
(on success or error) and block returning. That way we can ensure that
the "hw" (or com in net80211 terms) is there when we return from attach
matching the expected FreeBSD driver behaviour.
