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.

59c6e3a58f Decouple iSCSI connection limits from defaults.
If initiator does not negotiate some parameter, it expects one to get
default value, not some unknown remote hardware limit.  On the side side,
if some parameter is negotiated, its default value from RFC should not
be used for anything.

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.

fd936afb97 ctld(8): Fix MaxBurstLength negotiation.

2317fdfa8c Don't cap FirstBurstLength to maximum MaxRecvDataSegmentLength claimed

We may need to pass negotiated value to kernel level, but so far it is
not necessary, since it does not use any new features without request.
