4c291cb857 Multiple fixes for rockchip iodomain driver:
- always initialize selector of voltage signaling standard.
  Various versions of U-boot leaves voltage signaling standard settings
  for PMUIO2 domain in different state.  Always initialize it
  into expected state.
- start the driver as early as possible, the IO domains should be
  initialized before other drivers are attached.
- rename RK3399 register to its name founds in TRM.

This is the second part of fixes for serial port corruption observed after
DT 5.6 import.

b19042cb01 Use universe-toolchain config(8)
This is a temporary hack to aid with config(8) changing in r360443.
It will not work for all cases.

env PATH is used because universe-toolchain is only built when worlds
are built, and then only if clang is needed, so it may not exist.

universe-toolchain needs to be expanded to always be built, inspected to
remove non-cross-build-safe tools, used for buildworld/buildkernel,
and potentially incremental build support.

18bcf5a07d Restore local kernel "prog" filtering lost in r332099.
This behavior is most relevant for ipfw(4) as documented in syslog.conf(5).
The recent addition of property-based regex filters in r359327 is a
fine workaround for this but the behavior was present since 1997 and
documented.

This only fixes local matching of the "kernel program". It does not
change the forwarded format at all. On the remote side it will still
be "kernel: ipfw:" and not be parsed as a kernel message. This matches
old behavior.

67c907653e diff(1): don't reject specifying the same format multiple times
This may happen, for instance, if one happens to have an alias of diff to
diff -up and attempts to specify the amount of context on top of that.

Aliases like this may cause other problems, but if they're really not ever
generating non-unified diffs then we should at least not break that
use-case.

In addition, we'll now pick up a format mismatch if -p is specified with
!contextual && !unified && !unset.

Fix up a small trailing whitespace nit in the tests while we're here, and
add tests to make sure that we can double up all the formatting options.

5ecf33c6c4 Get rid of uio_XXX macros used for the Mac OS/X port.
The NFS code had a bunch of Mac OS/X accessor functions named uio_XXX
left over from the port to Mac OS/X. Since that port is long forgotten,
replace the calls with the code generated by the FreeBSD macros for these

0306689367 Fix sosend_generic() so that it can handle a list of ext_pgs mbufs.
Without this patch, sosend_generic() will try to use top->m_pkthdr.len,
assuming that the first mbuf has a pkthdr.
When a list of ext_pgs mbufs is passed in, the first mbuf is not a
pkthdr and cannot be post-r359919.  As such, the value of top->m_pkthdr.len
is bogus (0 for my testing).
This patch fixes sosend_generic() to handle this case, calculating the
total length via m_length() for this case.

There is currently nothing that hands a list of ext_pgs mbufs to
sosend_generic(), but the nfs-over-tls kernel RPC code in
projects/nfs-over-tls will do that and was used to test this patch.

f1f9347546 Initial support for kernel offload of TLS receive.
- Add a new TCP_RXTLS_ENABLE socket option to set the encryption and
  authentication algorithms and keys as well as the initial sequence
  number.

- When reading from a socket using KTLS receive, applications must use
  recvmsg().  Each successful call to recvmsg() will return a single
  TLS record.  A new TCP control message, TLS_GET_RECORD, will contain
  the TLS record header of the decrypted record.  The regular message
  buffer passed to recvmsg() will receive the decrypted payload.  This
  is similar to the interface used by Linux's KTLS RX except that
  Linux does not return the full TLS header in the control message.

- Add plumbing to the TOE KTLS interface to request either transmit
  or receive KTLS sessions.

- When a socket is using receive KTLS, redirect reads from
  soreceive_stream() into soreceive_generic().

- Note that this interface is currently only defined for TLS 1.1 and
  1.2, though I believe we will be able to reuse the same interface
  and structures for 1.3.

bhyve uses cached copies of the MSI capability registers to generate
MSI interrupts for device models.  Previously, these cached fields
were only set when the MSI capability control register was updated.
The Linux kernel recently adopted a change to deal with races in MSI
interrupt delivery that writes to the MSI capability address and data
registers to alter the destination of MSI interrupts without writing
to the MSI capability control register.  bhyve was not updating its
cached registers for these writes and continued to send interrupts
with the old data value to the old address.  Fix this by recomputing
the cached values for every write to any MSI capability register.

45818bf1a0 iflib: Stop interface before (un)registering VLAN
This patch is intended to solve a specific problem that iavf(4)
encounters, but what it does can be extended to solve other issues.

To summarize the iavf(4) issue, if the PF driver configures VLAN
anti-spoof, then the VF driver needs to make sure no untagged traffic is
sent if a VLAN is configured, and vice-versa. This can be an issue when
a VLAN is being registered or unregistered, e.g. when a packet may be on
the ring with a VLAN in it, but the VLANs are being unregistered. This
can cause that tagged packet to go out and cause an MDD event.

To fix this, include a new interface-dependent function that drivers can
implement named IFDI_NEEDS_RESTART(). Right now, this function is called
in iflib_vlan_unregister/register() to determine whether the interface
needs to be stopped and started when a VLAN is registered or
unregistered. The default return value of IFDI_NEEDS_RESTART() is true,
so this fixes the MDD problem that iavf(4) encounters, since the
interface rings are flushed during a stop/init.

A future change to iavf(4) will implement that function just in case the
default value changes, and to make it explicit that this interface reset
is required when a VLAN is added or removed.
