1de7b4b805 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.

a15fbc904a Alike to r312190 decouple iSCSI connection limits from defaults.
Connection parameters should remain at defaults until negotiated.

While there, remove sythetic limits, applied if kernel provided none.
iscsid has no own limitations, no configuration and no any idea what
values are good.  Assume kernel knows what it requests.

97b84d344d 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.

b1f92fa229 META MODE: Update dependencies with 'the-lot' and add missing directories.
This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so.  A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR.  These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package.  The current implementation of targets/ is
very unmaintainable.

Currently rescue/rescue and sys/modules are still not connected.

While we don't support MCS, hole in received sequence numbers may mean

connection to avoid stuck commands.

While there, improve handling of sequence numbers wrap after 2^32 PDUs.

8b94b5836c For both iSCSI initiator and target increase socket buffer sizes before
establishing connection.

This is a workaround for Chelsio TOE driver, that does not update socket
buffer size in hardware after connection established, and unless that is
done beforehand, kernel code will stuck, attempting to send/receive full
PDU at once.
