Extended atomics are supported with RC and XRC QP types, but Linux commit
a60109dc9a95 added an unneeded check to to_mlx5_access_flags().
This broke XRC QPs.
The following ib_atomic_bw invocation over XRC reproduces the issue:
ib_atomic_bw -d mlx5_1 --connection=XRC --atomic_type=FETCH_AND_ADD
It is safe to remove such checks because the QP type was already checked
in ib_modify_qp_is_ok(), which was previously called from
mlx5_ib_modify_qp().

In cm_form_tid(), a two bit message sequence number is OR'ed into bit
31-30 of the lower TID value.
After Linux commit f06d26537559 ("IB/cm: Randomize starting comm ID"), the
local_id is XOR'ed with a 32-bit random value. Hence, bit 31-30 in the
lower TID now has an arbitrarily value and it makes no sense to OR in
the message sequence number.
Adding to that, the evolution in use of IDR routines in cm_alloc_id()
has always had the possibility of returning a value with bit 30 set.
In addition, said bits are never checked.
Hence, remove the encoding and the corresponding enum.

The maximum page size in the mkey context is 2GB.
Until today, we didn't enforce this requirement in the code, and therefore,
if we got a page size larger than 2GB, we have passed zeros in the
log_page_shift instead of the actual value and the registration failed.
This patch limits the driver to use compound pages of 2GB for mkeys.

The patch simplifies mlx5_ib_cont_pages and fixes the following
issues in the original implementation:
First issues is related to alignment of the PFNs. After the check
base + p != PFN, the alignment of the PFN wasn't checked. So the PFN
sequence 0, 1, 1, 2 would result in a page_shift of 13 even though
the 3rd PFN is not 8KB aligned.
This wasn't actually a bug because it was supported by all the
existing mlx5 compatible device, but we don't want to require
this support in all future devices.
Another issue is because the inner loop didn't advance PFN so
the test "if (base + p != pfn)" always failed for SGE with
len > (1<<page_shift).

On some environments, such as certain SRIOV VF configurations, RoCE is
not supported for mlx5 Ethernet ports. Currently, the driver will not
open IB device on that port.
This is problematic, since we do want user-space RAW Ethernet (RAW_PACKET
QPs) functionality to remain in place. For that end, enhance the relevant
driver flows such that we do create a device instance in that case.

NanoBSD has helper script "fill_pkg.sh" which links all packages and
ther dependencies from "package dump" (like /usr/ports/packages/All) to
specified director. fill_pkg.sh has some limitations:
1) It needs ports tree, which should have exactly same versions as
"package dump".
2) It requires full paths to needed ports, including "/usr/ports" part.
3) It has assumptions about Nano Package Dir (it assumes, that it
specified rtelative to current directory).
4) It does not have any diagnostics (almost).
This PR enhances "fill_pkg.sh" script in several ways:
1) Nano package dir could be absolute path.
2) Script understands four ways to specify "root" ports/packages:
(a) Absolute directory with port (old one)
(b) Relative directory with port, relative to ${PORTSDIR} or /usr/ports
(c) Absolute path to file with package (with .tbz suffix)
(d) Name of package in dump dir, with or without .tbz suffix
These ways can be mixed in one call. Dependencies for
packages are obtained with 'pkg_info -r' call, and are searched for
in same directory as "parent" package. Dependencies for ports are
obtained in old way from port's Makefile.
3) Three levels of diagnostic (and -v option, could be repeated) are added.
4) All path variables are enclosed in quotes, to make script work with paths,
containing spaces.
Note: imp merged in the changes to fill_pkg.sh since this has been a PR.

Large nextboot.conf files (over 80 bytes) are not read correctly by the
Forth loader, causing file parsing to abort, and nextboot configuration
fails to apply.
Simple repro:
nextboot -e foo=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
shutdown -r now
That will cause the bug to cause a parse failure but shouldn't otherwise
affect the boot. Depending on your loader configuration, you may also
have to set beastie_disable and/or reduce the number of modules loaded
to see the error on a small console screen. 12.0 or CURRENT users will
also have to explicitly use the Forth loader instead of the Lua loader.
The error will look something like:
Warning: syntax error on file /boot/loader.conf.local
foo="xxxxxxxxxxxxxxnextboot_enable="YES"
^
/boot/support.4th has crude file I/O buffering, which uses a buffer
'read_buffer', defined to be 80 bytes by the 'read_buffer_size'
constant. The loader first tastes nextboot.conf, reading and parsing
the first line in it for nextboot_enable="YES". If this is true, then
it reopens the file and parses it like other loader .conf files.
Unfortunately, the file I/O buffering code does not fully reset the
buffer state in the reset_line_reading word. If the last file was read
to the end, that doesn't matter; the file buffer is treated as empty
anyway. But in the nextboot.conf case, the loader will not read to the
end of file if it is over 80 bytes, and the file buffer may be reused
when reading the next file. When the file is reread, the corrupt text
may cause file parsing to abort on bad syntax (if the corrupt line has
<>2 quotes in it), the wrong variable to be set, no variable to be set
at all, or (if the splice happens to land at a line ending) something
approximating normal operation.
The bug is very old, dating back to at least 2000 if not before, and is
still present in 12.0 and CURRENT r345863 (though it is now hidden by
the Lua loader by default).
Suggested one-line attached. This does change the behavior of the
reset_line_reading word, which is exported in the line-reading
dictionary (though the export is not documented in loader man pages).
But repo history shows it was probably exported for the PNP support
code, which was never included in the loader build, and was removed 5
months ago.
One thing that puzzles me: how has this bug gone unnoticed/unfixed for
nearly 2 decades? I find it hard to believe that nobody's tried to do
something interesting with nextboot, like load a kernel and filesystem,
which is what I'm doing.

Callers of zfs_file_get and zfs_file_put can corrupt the reference
counts for the file structure resulting in a panic or a soft lockup.
When zfs send/recv runs, it will add a reference count to the
open file, and begin to send or recv the stream. If the file descriptor
is closed, then when dmu_recv_stream() or dmu_send() return we will
call zfs_file_put to remove the reference we placed on the file
structure. Unfortunately, because zfs_file_put() uses the file
descriptor to lookup the file structure, it may end up finding that
the file descriptor table no longer contains the file struct, thus
leaking the file structure. Or it might end up finding a file
descriptor for a different file and blindly updating its reference
counts. Other failure modes probably exists.
This change reworks the zfs_file_[get|put] interface to not rely
on the file descriptor but instead pass the zfs_file_t pointer around.
