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.

629aa519d6 Make tsec work with the device tree present on the RB800. The previous code
assumed that the MDIO bus was a direct child of the Ethernet interface. It
may not be and indeed on many device trees is not. While here, add proper
locking for MII transactions, which may be on a bus shared by several MACs.

bd37530ee4 Additional features for the tsec(4) Ethernet driver.
- interrupt coalescing
  - polling
  - jumbo frames
  - multicast
  - VLAN tagging

The enhanced version of the chip (eTSEC) can also take advantage of:

  - TCP/IP checksum calculation h/w offloading

67196661ab Support for Freescale integrated Three-Speed Ethernet Controller (TSEC).
TSEC is the MAC engine offering 10, 100 or 1000 Mbps speed and is found on
different Freescale parts (MPC83xx, MPC85xx). Depending on the silicon version
there are up to four TSEC units integrated on the chip.

This driver also works with the enhanced version of the controller (eTSEC),
which is backwards compatible, but doesn't take advantage of its additional
features (various off-loading mechanisms) at the moment.
