iscsi cls session
private driver data size
This can be called from a LLD or iscsi_transport. The connection is child of the session so cid must be unique for all connections on the
Since we do not support MCS, cid will normally be zero. In some cases for software iscsi we could be trying to preallocate a connection
struct in which case there could be two connection structs and cid would be non-zero.

iscsi -- iSCSI initiator
To compile this driver into the kernel, place the following line in the kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
The iscsi subsystem provides the kernel component of an iSCSI initiator. The initiator is the iSCSI client, which connects to an iSCSI tar-
get, providing local access to a remote block device. The userland component is provided by iscsid(8) and both the kernel and userland are
configured using iscsictl(8). The iscsi subsystem is responsible for implementing the "Full Feature Phase" of the iSCSI protocol.
The following variables are available as both sysctl(8) variables and loader(8) tunables:
The number of seconds to wait for the target to respond to a NOP-Out PDU. In the event that there is no response within that time
the session gets forcibly restarted.
The number of seconds to wait for ctld(8) to establish a session. After that time iscsi will abort and retry.
The number of seconds to wait for a login attempt to succeed. After that time iscsi will abort and retry.
The maximum number of outstanding IO requests.
Controls the behavior after an iSCSI connection has been dropped due to network problems. When set to 1, a dropped connection causes
the iSCSI device nodes to be destroyed. After reconnecting, they will be created again. By default, the device nodes are left
intact. While the connection is down all input/output operations are suspended, to be retried after the connection is reestablished.

The iscsi subsystem first appeared in FreeBSD 10.0.
The iscsi subsystem was developed by Edward Tomasz Napierala <trasz@FreeBSD.org> under sponsorship from the FreeBSD Foundation.
