48133c3ff3 Delete the undocumented alias 'wds'.
This was a typo for wdc. Eliminate it since it was in error. People
should use either 'wdc' or 'hgst' for the vendor from now on. 'hgst'
works for all versions this functionality is present for.

a13a291adf Move nvmecontrol to using linker sets for commands
More commands will be added to nvmecontrol. Also, there will be a few
more vendor commands (some of which may need to remain private to
companies writing them). The first step on that journey is to move to
using linker sets to dispatch commands. The next step will be using
dlopen to bring in the .so's that have the command that might need
to remain private for seamless integration.

Similar changes to this will be needed for vendor specific log pages.

9544e6dcf1 Make NVMe compatible with the original API
The original NVMe API used bit-fields to represent fields in data
structures defined by the specification (e.g. the op-code in the command
data structure). The implementation targeted x86_64 processors and
defined the bit fields for little endian dwords (i.e. 32 bits).

This approach does not work as-is for big endian architectures and was
changed to use a combination of bit shifts and masks to support PowerPC.
Unfortunately, this changed the NVMe API and forces #ifdef's based on
the OS revision level in user space code.

This change reverts to something that looks like the original API, but
it uses bytes instead of bit-fields inside the packed command structure.
As a bonus, this works as-is for both big and little endian CPU
architectures.

2bac48c266 Print Maximum Data Transfer Size as a long rather than int
PowerPC has PAGE_SIZE as a long, not an int.  This causes the compiler to throw
a format mismatch warning on this print.  To work around the difference, print
it as a long instead of an int, and force the argument to a long.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

After review by the WDC engineers, improve how we pull down the
so-called 'e6' logs. The 'c6' logs are obsolete and support for them
has been removed because FreeBSD needed to pull them in chunks, which
is incompatible with the 0xc6 opcode implementation. Rather than leave
the code in place that produces bad log pulls, remove it.

4e44c386ff i386 turns out to not have __uint128_t. So confusingly use 64-bit math
instead. Since we're little endian, we can get away with it. Also,
since the counters in quesitons would require billions of iops for
tens of billions of seconds to overflow, and since such data rates are
unlikely for people using i386 for a while, that's OK. The fastest
cards today can't do even a million IOPs.
