0064919585 Add network QoS support for PCP to iscsi initiator.
Make the Ethernet PCP codepoint configurable
for L2 local traffic, to allow lower latency for
iSCSI block IO. This addresses the initiator
side only.

76f370dc71 Add DSCP support for network QoS to iscsi initiator.
Allow the DSCP codepoint also to be configurable
for the traffic in the direction from the initiator
to the target, such that writes and any requests
are also treated in the appropriate QoS class.

7551d83c35 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.

2e36f0c10a Make the iSCSI parameter negotiation more flexible.
Decouple the send and receive limits on the amount of data in a single
iSCSI PDU.  MaxRecvDataSegmentLength is declarative, not negotiated, and
is direction-specific so there is no reason for both ends to limit
themselves to the same min(initiator, target) value in both directions.

Allow iSCSI drivers to report their send, receive, first burst, and max
burst limits explicitly instead of using hardcoded values or trying to
derive all of them from the receive limit (which was the only limit
reported by the drivers prior to this change).

Display the send and receive limits separately in the userspace iSCSI
utilities.

57b120baca Add "iscsictl -e". Among other things, it makes it possible to perform
discovery without attaching to the targets ("iscsictl -Ad ... -e off"),
and then attach to selected ones ("iscsictl -Mi ... -e on").

a2213e2bd1 There is no need to prevent iscsictl from adding iSER session when there
is no iSER support in ctld and/or kernel; should the user make that mistake,
the output from "iscsictl -L" is enough to determine what the problem is.

b49e1028bf Rename '-h' option to '-p', and use "portal" instead of "host" or "address",
in order to be consistent with iSCSI terminology.  Besides, calling the
option '-h' was just wrong.

This changes usage for newly added iscsictl(8), and two newly added
subcommands to ctladm(8).  This breaks POLA between CURRENT and 10,
but since 10.0 has not been released yet, it's still ok to do.
