718cf2ccb9 sys/dev: further 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.

ecfb79144f sfxge(4): fix RxQ structure layout vs usage on datapath
Recent changes in the pseudo header accessor prototypes start to
use common code RxQ handle on datapath. The handle was located
at the end of the structure with members not used on datapath.
