sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

1. state checks in bxe_tx_mq_start_locked() and bxe_tx_mq_start() to sync threads during interface down or detach.
2. add sysctl to set pause frame parameters
3. increase max segs for TSO packets to BXE_TSO_MAX_SEGMENTS (32)
4. add debug messages for PHY
5. HW LRO support restricted to FreeBSD versions 8.x and above.
