* flesh out a "get default DFS parameters" routine
* remove the stub that returns NULL
* fix up the enable DFS method to do what FreeBSD does - specifically, allow pe_enabled
to be set/cleared.
This allows the radar pulse reporting code to function, but it doesn't yet
do anything useful.
* add debugging
* disable the manual noise floor calibration and tracking done by the HAL;
this interferes with the normal calibration path and will lock up the RX
side
* don't program short report / priority if they're provided as NOVAL.
under a shared read lock. This patch attempts to upgrade the lock to
an exclusive write lock. If the exclusive write lock fails to be
obtained, the current fragment is not placed at the head of the list.
This portion of the patch was inspired by NetBSD ip_frag.c r1.4 (which
effectively removed the section of code that performed the reordering).
The patch to sys/contrib/ipfilter/netinet/ip_compat.h adds the
MUTEX_TRY_UPGRADE macro to support the patch to ip_frag.c.
The patch to contrib/ipfilter/lib/rwlock_emul.c supports this patch
by emulating the mutex in userspace when exercised by ipftest(1).

Languages like C++17 and Go provide direct support for slice types:
pointer/length pairs. The CloudABI generator now has more complete for
this, meaning that for the C binding, pointer/length pairs now use an
automatic naming scheme of ${name} and ${name}_len.
Apart from this change and some reformatting, the ABI definitions are
identical. Binary compatibility is preserved entirely.
Include netinet/in.h before ip_compat.t which will then check if
IPPROTO_IPIP is defined or not. Doing it the other way round,
ip_compat.h would not find it defined and netinet/in.h then
redefine it.
Although vchiq_build_date and vchiq_build_time are not used in current
vchi driver at the moment, make sure these value will not leak into
build later on if at some point they will be refered in some new
imported code

Drop the tracking down to the pmap layer, with optimizations to only track
necessary pages. This should give a (slight) performance improvement, as well
as a stability improvement, as the tracking is already mostly handled by the
pmap layer.
As part of an effort to extend Book-E to the 64-bit world, make the necessary
changes to the DPAA/dTSEC driver set to be integer-pointer conversion clean.
This means no more casts to int, and use uintptr_t where needed.
Since the NCSW source is effectively obsolete, direct changes to the source tree
are safe.
All devices:
- 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:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn rtwnfw -> rtwn rtwn_pci rtwnfw
Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.

Linux's copy of the Cavium SDK does not have these non-ASCII characters

Don't call pmap_kextract() multiple times, it wastes CPU cycles, which in a high
performance environment can be very expensive.
Inline XX_FindTracker() to allow more optimizations as well.
Since if_addrlist is used only for ipfilter(4), add a macro if_addrlist
in ip_compat.h.

- Use conditional instruction to simplify the ARMv6 vDSO. This means
that we no longer perform any branching. In the failure case, we
simply slide over the assignments of the return values.
The vDSO could be improved even further by using stmia to do
assignments in parallel. Unfortunately, the script used to generate
these is not smart enough for that (yet).
Spotted by: andrew@.
- Make the style of the i686 vDSO more similar to the others by using
decimal literals.
Bugs in the Python code used to generate this vDSO caused us to
miscompute the register numbers/stack offsets at which addresses of the
system call output arguments were stored.
Together with some other patches, this vDSO allows us to make all of the
cloudlibc unit tests pass.

In order to make CloudABI work on ARMv6, start off by copying over the
sysvec for ARM64 and adjust it to use 32-bit registers. Also add code
for fetching arguments from the stack if needed, as there are fewer
register than on ARM64.
Also import the vDSO that is needed to invoke system calls. This vDSO
uses the intra procedure call register (ip) to store the system call
number. This is a bit simpler than what native FreeBSD does, as FreeBSD
uses r7, while preserving the original r7 into ip.
This sysvec seems to be complete enough to start CloudABI processes.
These processes are capable of linking in the vDSO and are therefore
capable of executing (most?) system calls successfully. Unfortunately,
the biggest show stopper is still that TLS is completely broken:
- The linker used by CloudABI, LLD, still has troubles with some of the
relocations needed for TLS. See LLVM bug 30218 for more details.
- Whereas FreeBSD uses the tpidruro register for TLS, for CloudABI I
want to make use of tpidrurw, so that userspace can modify the base
address directly. This is needed for efficient emulation.
Unfortunately, this register doesn't seem to be preserved across
context switches yet.
