sources to return timestamps when SO_TIMESTAMP is enabled. Two additional
clock sources are:
o nanosecond resolution realtime clock (equivalent of CLOCK_REALTIME);
o nanosecond resolution monotonic clock (equivalent of CLOCK_MONOTONIC).
In addition to this, this option provides unified interface to get bintime
(equivalent of using SO_BINTIME), except it also supported with IPv6 where
SO_BINTIME has never been supported. The long term plan is to depreciate
SO_BINTIME and move everything to using SO_TS_CLOCK.
Idea for this enhancement has been briefly discussed on the Net session
during dev summit in Ottawa last June and the general input was positive.
This change is believed to benefit network benchmarks/profiling as well
as other scenarios where precise time of arrival measurement is necessary.
There are two regression test cases as part of this commit: one extends unix
domain test code (unix_cmsg) to test new SCM_XXX types and another one
implementis totally new test case which exchanges UDP packets between two
processes using both conventional methods (i.e. calling clock_gettime(2)
before recv(2) and after send(2)), as well as using setsockopt()+recv() in
receive path. The resulting delays are checked for sanity for all supported
clock types.

vmpage requires struct pmap to exist and contain a pm_stats field. As of
r308817, either AIM or BOOKE is required to be set in order to get their
respective pmap structs. Rather than expose them both, or try to unify them
unnecessarily, add a third option which contains only a pm_stats field, and
change the two existing pmap structures to place the common fields at the
beginning of the struct. This actually fixes the stats collection by libkvm on
AIM hardware, because before it was accessing a possibly different offset, which
would cause it to read garbage.
Bump __FreeBSD_version to denote this ABI change, so that ports which depend on
libkvm can be rebuilt.
Allow -B to mean -K -W.
There are times when fixing non-base elementes of the build that you
don't want to wait to get a completely clean world install. This
allows that at the cost of a little danger.

In a git worktree, the gitdir is in an entirely different location.
In arcgit, use git rev-parse --git-dir to get the correct path to it
always.
When running git from outside of the work tree, as in importgit,
the path provided by git rev-parse --git-dir can be either a
relative or absolute path depending on the work tree. Rather
than trying to deal with that, just use git -C.

- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
* for RTL8821AU: 2 VAPs at the same time;
* other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
* bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
* common (if_rtwn*)
* chip-specific (rtl*/*)
- various other bugfixes.
Due to code reorganization, module names / requirements were changed too:

This commit, long overdue, contains contributions in the last 2 years
from Stefano Garzarella, Giuseppe Lettieri, Vincenzo Maffione, including:
+ fixes on monitor ports
+ the 'ptnet' virtual device driver, and ptnetmap backend, for
high speed virtual passthrough on VMs (bhyve fixes in an upcoming commit)
+ improved emulated netmap mode
+ more robust error handling
+ removal of stale code
+ various fixes to code and documentation (some mixup between RX and TX
parameters, and private and public variables)
We also include an additional tool, nmreplay, which is functionally
equivalent to tcpreplay but operating on netmap ports.
