There is no point to do it. The VNON type is good enough for fdescfs
operations, and changing the type on stat(2) is arbitrary and does not
serve much purpose, because we recalculate the returned file type on
each stat(2) anyway.
But setting the type to VLNK has undesired consequence of namei()
trying VOP_READLINK() there, which might fail since it defer the
calculation of path to vn_fullpath().

Enable the FMan hardware parser to take advantage of some offloading.
This enables receive and transmit checksum offloading for both IPv4 and
IPv6.
Additional offloading capabilities the DPAA supports include:
* vlan parsing
* Transmit rate limiting
* IEEE-1588 timestamps
* Soft parsing for custom protocol checking
* Congestion handling
The NCSW reference base requires tuning for each target, and currently
is configured for FMANv2. This doesn't readily work on FMANv3 devices,
such as the T-series powerpc, or the LS1043 ARM. Since Freescale/NXP
abandoned the NCSW driver a decade ago, it makes sense to abandon it
ourselves as well. This new driver uses a combination of the NCSW
driver and the Linux driver (BSD/GPL dual licensed) as a reference, but
contains no actual code from them.
The DPAA (Data Path Acceleration Architecture) subsystem consists of the
following components:
* BMan -- Buffer Manager. Manages buffer pools of different sizes (one
size per pool, up to 64 pools)
* QMan -- Queue Manager. Manages the interfaces between DPAA-based
components and the CPU(s).
* FMan -- Frame Manager. Responsible for all ethernet-related
processing. Consists itself of the following components:
* Ports -- interfaces to the QMan. An ethernet interface consists of
2 ports.
Ports use "Next-invoked action" (NIA) descriptors to form a pipeline
for processing on receive and transmit.
* Parser -- performs protocol header parsing and validation. Both
hardware and software parsers are available.
* KeyGen -- Key generator, used to start the classification process
(for the Policer), generating FQIDs and other keys based on the
frame input.
* Policer -- performs traffic shaping and classification
* MAC -- SoC specific ethernet MAC (dTSEC, TGEC, mEMAC). Currently
supports dTSEC and mEMAC, along with their MDIO blocks.
Additional components not yet handled:
SEC -- Security engine (crypto)
RE -- RAID engine
RapidIO
DCE -- Decompression/Compression engine, supports ZLIB, DEFLATE, and
GZIP, as well as base64 encoding and decoding.
BMan and QMan are accessed via cache-coherent portals, using ring
buffers as I/O. The intent is for portals to be per-CPU (core/thread)
to reduce locking contention and improve performance. This driver pins
interrupt handlers to the CPU "owning" a given portal, and uses critical
sections to prevent switching while accessing the portal.
Three architecture dependent manuals are installed to MANSUBDIRs,

installed, and noted at the top of the rendered manual.

For unicast tests, it is sufficient to use wait_for_carp() to verify
the setup is sane. Additional sanity checks are not necessarily
required but can serve purpose for redundancy.
For some unclear reason routed(8) is advertising route to carp BACKUP.
That makes the test flaky. Also routed(8) is marked deprecated and may
be removed from base in the future. Let's just add static route entry
manually for additional sanity checks.
Other noticeable changes:
1. Add atf_check to configuration steps to prevent potential failure
on setup. That helps diagnosing on failure.
2. Shorten the names of jails to improve readability.
3. Prefer `[ifconfig|route|sysctl] -j` over `jexec [ifconfig|route|sysctl]`
to make the lines shorter.

When the nfsd was vnet'd, the VNET macros were hidden
behind macros that had the NFSD_ prefix on them.
This was done because, at the time, it was thought
that something other than vnet might be used for this.
That has not happened and probably will not happen,
so this patch replaces these obscuring macros with
the regular vnet ones.
There should be no semantics change caused by

Without this patch, all upcalls to the gssd daemon are
done in vnet0 (outside of any vnet jail). This does
not work well, because a user principal's credential
cache can be within the jail (/tmp/krb5cc_NNN in the
jail's namespace).
This patch modifies the client so that RPCs done
from within vnet jails does an upcall to a gssd
daemon running within the vnet jail. It required
that the cache of uid->credential shorthands in
the rpcsec_gss be vnet'd.
The situation is still less than ideal and sec=krb5[ip]
mounts that are visible within vnet jails is still
not something I would recommend, but it can work ok
with this patch.
Vnet'ng the NFS client so that mounts can be done
within vnet jails is probably more useful, but that
will require additional work.

Fix this behavior by handling that ImportError well enough to list test

RFC 792 defines the ICMP Originate Timestamp field as milliseconds
since midnight UTC. However, ping(8) currently derives this value
from CLOCK_MONOTONIC, which represents time since an unspecified
starting point and is not related to UTC.
The issue was introduced by commit 1ad76f1b60, which replaced
gettimeofday(2) with clock_gettime(CLOCK_MONOTONIC) for timekeeping
in ping(8).
Fix this by using CLOCK_REALTIME when generating the ICMP originate
timestamp.

D40479 changed namei() so that an absolute symlink target
encountered during an ABI-root lookup restarts from the native root.
This helps the native fallback case, but it also makes successful
lookups inside an ABI root escape that root while following absolute
symlinks.
Only switch absolute symlink lookup to the native root after namei()
is already in the restarted/native fallback pass.
Do not mark the lookup as restarted merely because an absolute
symlink was encountered while still resolving inside the ABI root.
This preserves the intended native fallback behavior while keeping
absolute symlinks within a successfully resolved ABI-root path in
the ABI namespace.
