sfxge(4): use n Tx queues instead of n + 2 on EF10 HW

On EF10 HW we can avoid sending packets without checksum offload
or with IP-only checksum offload to dedicated queues. Instead, we
can use option descriptors to change offload policy on any queue
during runtime. Thus, we don't need to create two dedicated queues.

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.
