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.

9613ad24b0 hyperv/vmbus: Allow bufrings preallocation.
The assumption that the channel is only opened upon synthetic device
attach time no longer holds, e.g. Hyper-V network device MTU changes.
We have to allow device drivers to preallocate bufrings, e.g. in
attach DEVMETHOD, to prevent bufring allocation failure once the
system memory is fragmented after running for a while.
