+nvme-dir-send - Issue a directive send command, returns applicable results

+SYNOPSIS

+[verse]
+'nvme dir-send' <device> [--namespace-id=<nsid> | -n <nsid>]
+			  [--data-len=<data-len> | -l <data-len>]
+			  [--dir-type=<dtype> | -D <dtype>]
+			  [--dir-spec=<dspec> | -S <dspec>]
+			  [--dir-oper=<doper> | -O <doper>]
+			  [--endir=<endir> | -e <endir>]

+			  [--human-readable | -H]
+			  [--raw-binary | -b]
+
+DESCRIPTION
+-----------
+Submits an NVMe Directive Send admin command and returns the applicable
+results. This may be the combination of directive type, and operation, as
+well as target directive and its enable/disable status of the operation,
+if specific operation needs it.
+
+The <device> parameter is mandatory and may be either the NVMe character
+device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).
+
+On success, the returned directive's parameter structure (if applicable) is
+returned in one of several ways depending on the option flags; the
+structure may parsed by the program and printed in a readable format
+if it is a known structure, displayed in hex, or the raw buffer may be
+printed to stdout for another program to parse.
+
+OPTIONS
+-------
+-n <nsid>::
+--namespace-id=<nsid>::
+	Retrieve the feature for the given nsid. This is optional and
+	most features do not use this value.
+
+-D <dtype>::
+--dir-type=<dtype>::
+	Directive type	
+
+-S <dspec>::
+--dir-spec=<dspec>::
+	Directive specific	
+
+-O <doper>::
+--dir-oper=<doper>::
+	Directive operation	
+
+-T <tdir>::
+--target-dir=<nsr>::
+	Target directive of the operation
+
+-e <endir>::
+--endir=<endir>::
+	Target directive enable(1) or disable (0) operation
+

+|==================
+
+-l <data-len>::
+--data-len=<data-len>::
+	The data length for the buffer returned for this feature. Most
+	known features do not use this value. The exception is LBA
+	Range Type
+
+-b::
+--raw-binary::
+	Print the raw receive buffer to stdout if the command returns
+	a structure.
+
+-H::
+--human-readable::
+	Print the decoded receive buffer to stdout if the command returns
+	a structure.
+
+EXAMPLES
+--------
+* Enable streams directive :
+
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 0 --dir-oper 1 --target-dir 1 --endir 1
+------------
+
+
+* Disable streams directive :
+
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 0 --dir-oper 1 --target-dir 1 --endir 0
+------------
+
+
+* Release all allocated streams resource :
+
+------------
+# nvme dir-send /dev/nvme0n1 --dir-type 1 --dir-oper 2
+------------
+
+
+* Release stream ID 3 :
+
+------------
+# nvme dir-send /dev/nvme0 --dir-type 1 --dir-oper 1 --dir-spec 3
+------------
+
+It is probably a bad idea to not redirect stdout when using this mode.
