X_ip_mrouter_done() was calling the interface ioctl routines via
if_allmulti() while holding a write lock. However, some interface
ioctl routines, including em/iflib and tap, use sxlocks, which are
not permitted while holding a non-sleepable lock, and this elicits
a warning from WITNESS. Fix the locking issue by recording the
affected interface pointers in a malloc'ed array, and call
if_allmulti() on each after dropping the rwlock.

This file holds a UUID that is invariant for every boot. In our case, it is

Inactive Ethernet rules get cleaned by a net_epoch callback. This
callback may still be pending when we try to start a new (pf rules)
transaction, causing it to fail.
This is especially likely to occur in scripted scenarios, such as the
regression tests.
Drain the epoch callbacks before starting a new transaction, ensuring
we've had the opportunity to clean up the inactive rules.

For IPv4 use dst pointer as destination address in fib4_lookup().
It keeps destination address from IPv4 header and can be changed
when PACKET_TAG_IPFORWARD tag was set by packet filter.
For IPv6 override destination address with address from dst_sa.sin6_addr,
that was set from PACKET_TAG_IPFORWARD tag.

Matching for DSCP codes has used incorrect bits. Use IPV6_DSCP()
macro for matching opcodes to fix this. Also this leads to always
use value from a mbuf instead of cached value.
Previously different opcodes have used both cached in f_id value
and stored in the mbuf, and it did not always work after setdscp
action, since cached value was not updated.
Update IPv6 flowid value cached in the f_id.flow_id6 when we do
modification of DSCP value in O_SETDSCP opcode, it may be used by
external modules.
Also added logging support for O_SETDSCP opcode.

The correct OID format for CTLTYPE_U64 is `QU` (`uquad_t`), not `A`
(text expressed via `char *`).
This issue was noticed while doing an sysctl tree walk using a
sysctl(9) consumer that relies on the OID format to intuit what the
type should be for a given sysctl.

The __diagused macro was used to cure a "set but not used" warning. This
broke the build for bhyve since __diagused is only defined in the
kernel. Define __diagused when not building the kernel.

The "void *stuff" (also called fstuff and dstuff) argument
was used by the Mac OSX port. For FreeBSD, this argument
is always NULL, so remove it to clean up the code.
This commit gets rid of "stuff" for nfscl_request().
Future commits will do the same for other functions.
On some hardware the EFI system table is not in memory mapped in the
DMAP section. Rather than panic the kernel check if it is mapped and
return a failure if not from efi_phys_to_kva.

Some UEFI implementations place the system table in a runtime code
memory region. Include it in the DMAP so we can read it later.

reporting the shapshot of the active advisory locks.
A new VFS ops method vfs_report_lockf if provided in the mount point
op table. If it is NULL, as it is currently for all existing
filesystems, vfs_report_lockf() function is used, which gathers
information from the standard implementation inside kern/kern_lockf.c.
Filesystems implementing its own locking (NFSv4 as example) can provide
a custom implementation.

The UFS-specific struct inode cannot be used in generic advisory lock
code. It was probably used as a shortcut for the debugging, as the
remnants of the code around it indicates.
Use somewhat more verbose and less concentrated, but universal,
VOP_PRINT(), where needed.
