The NVME standard has required in section 7.2.6, since at least 1.1, that a clean shutdown is signalled by deleting the subission and the completion queues before setting the shutdown bit in CC. The 1.0 standard, apparently, did not and many of the early Intel cards didn't care. Some newer cards care, at least one whose beta firmware can scramble the card on an unclean shutdown. Linux has done this for some time. To make it possible to move forward with an evaluation of this pre-release card with wonky firmware, delete the queues on the card when we delete the qpair structures. Sponsored by: Netflix

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
