nmix is used to compare against oss_mixerinfo->dev, which is a
user-supplied value to select the mixer device (if not -1, in which case
we'll select the default one) we want to fetch the information of. It is
also used to set oss_mixerinfo->dev in case it is -1.
However, nmix is at best redundant, since we have the loop counter
already (i), and confusing at worst.
For example, suppose a system with 3 mixer devices. We call
SNDCTL_MIXERINFO with oss_mixerinfo->dev=1, meaning we want to get
information for /dev/mixer1. Suppose /dev/mixer0 detaches while inside
the loop, so we'll hit the loop's "continue" case, and nmix won't get
incremented (i.e will stay 0 for now). At this point nmix counts 1
device less, so when it reaches 1, we'll be fetching /dev/mixer2's
information instead of /dev/mixer1's.
This is also true in case the mixer device disappears prior to the call
to mixer_oss_mixerinfo().
Simply remove nmix and use the loop counter to both set
oss_mixerinfo->dev and check against it in case a non -1 value is
supplied.

Add a sound(4) bridge device driver for the RME HDSP 9632 and HDSP 9652
sound cards. These cards require a nowadays rare PCI 32bit (not PCIe)
slot, but still see use due to their value and wealth of features.
The HDSP 9632 is mostly comparable to the newer HDSPe AIO, while the
HDSP 9652 is similar to the HDSPe RayDAT. These HDSPe PCIe cards are
supported by the snd_hdspe(4) driver which was taken as a starting point
for development of snd_hdsp(4).
Implementation is kept separately due to substantial differences in
hardware configuration and to allow easy removal in case PCI 32bit
support would be phased out in the future.
The snd_hdsp(4) kernel module is not enabled by default, and can be
loaded at runtime with kldload(8) or during boot via loader.conf(5).
Basic operation was tested with both cards, not including all optional
cable connectors and expansion boards. Features should be roughly on par
with the snd_hdspe(4) supported cards.

This is the client (initiator in SCSI terms) for NVMe over Fabrics.
Userland is responsible for creating a set of queue pairs and then
handing them off via an ioctl to this driver, e.g. via the 'connect'
command from nvmecontrol(8). An nvmeX new-bus device is created
at the top-level to represent the remote controller similar to PCI
nvmeX devices for PCI-express controllers.
As with nvme(4), namespace devices named /dev/nvmeXnsY are created and
pass through commands can be submitted to either the namespace devices
or the controller device. For example, 'nvmecontrol identify nvmeX'
works for a remote Fabrics controller the same as for a PCI-express
controller.
nvmf exports remote namespaces via nda(4) devices using the new NVMF
CAM transport. nvmf does not support nvd(4), only nda(4).

Structurally this is very similar to the TCP transport for iSCSI
(icl_soft.c). One key difference is that NVMeoF transports use a more
abstract interface working with NVMe commands rather than transport
PDUs. Thus, the data transfer for a given command is managed entirely
in the transport backend.
Similar to icl_soft.c, separate kthreads are used to handle transmit
and receive for each queue pair. On the transmit side, when a capsule
is transmitted by an upper layer, it is placed on a queue for
processing by the transmit thread. The transmit thread converts
command response capsules into suitable TCP PDUs where each PDU is
described by an mbuf chain that is then queued to the backing socket's
send buffer. Command capsules can embed data along with the NVMe
command.
On the receive side, a socket upcall notifies the receive kthread when
more data arrives. Once enough data has arrived for a PDU, the PDU is
handled synchronously in the kthread. PDUs such as R2T or data
related PDUs are handled internally, with callbacks invoked if a data
transfer encounters an error, or once the data transfer has completed.
Received capsule PDUs invoke the upper layer's capsule_received
callback.
struct nvmf_tcp_command_buffer manages a TCP command buffer for data
transfers that do not use in-capsule-data as described in the NVMeoF
spec. Data related PDUs such as R2T, C2H, and H2C are associated with
a command buffer except in the case of the send_controller_data
transport method which simply constructs one or more C2H PDUs from the
caller's mbuf chain.

nvmf_transport.ko provides routines for managing NVMeoF queue pairs
and capsules. It provides a glue layer between transports (such as
TCP or RDMA) and an NVMeoF host (initiator) and controller (target).
Unlike the synchronous API exposed to the host and controller by
libnvmf, the kernel's transport layer uses an asynchronous API built
on callbacks. Upper layers provide callbacks on queue pairs that are
invoked for transport errors (error_cb) or anytime a capsule is
received (receive_cb).
Data transfers for a command are usually associated with a callback
that is invoked once a transfer has finished either due to an error
or successful completion.
For an upper layer that is a host, command capsules are allocated and
populated with an NVMe SQE by calling nvmf_allocate_command. A data
buffer (described by a struct memdesc) can be associated with a
command capsule before it is transmitted via nvmf_capsule_append_data.
This function accepts a direction (send vs receive) as well as the
data transfer callback. The host then transmits the command via
nvmf_transmit_capsule. The host must ensure that the data buffer
described by the 'struct memdesc' remains valid until the data
transfer callback is called. The queue pair's receive_cb callback
should match received response capsules up with previously transmitted
commands.
For the controller, incoming commands are received via the queue
pair's receive_cb callback. nvmf_receive_controller_data is used to
retrieve any data from a command (e.g. the data for a WRITE command).
It can be called multiple times to split the data transfer into
smaller sizes. This function accepts an I/O completion callback that
is invoked once the data transfer has completed.
nvmf_send_controller_data is used to send data to a remote host in
response to a command. In this case a callback function is not used
but the status is returned synchronously. Finally, the controller can
allocate a response capsule via nvmf_allocate_response populated with
a supplied CQE and send the response via nvmf_transmit_capsule.
