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.

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

Add optional support to mxge for MSI-X interrupts and multiple receive
queues (which we call slices). The NIC will steer traffic into up to
hw.mxge.max_slices different receive rings based on a configurable
hash type (hw.mxge.rss_hash_type).

Currently the driver defaults to using a single slice, so the default
behavior is unchanged. Also, transmit from non-zero slices is
disabled currently.

Improve mxge receive performance:

receive mode which allows us to use FreeBSD's physically discontinuous
MJUM9BYTES clusters.

- Switch the driver from chaining MJUMPAGESIZE clusters to using
MJUM9BYTES clusters to avoid mbuf chaining overheads. Due to this
change, people running obsolete f/w images will be limited to an MTU of
PAGE_SIZE - 16.

- Add (disabled by default) support for Large Receive Offload.

Firmware update & improvements to firmware selection:

- Use the new MXGEFW_CMD_UNALIGNED_TEST (added in firmare 1.4.16) to
have the firmware tell us if the PCIe chipset supports aligned PCIe
completions.

- Hard to maintain, and frequently out of date whitelist of PCIe
chipsets known to produce aligned completions removed, as it has been
replaced in its role of selecting the correct firmware to run by the
use of MXGEFW_CMD_UNALIGNED_TEST.

- Break the dma test out of mxge_reset() and into its own function
(mxge_dma_test()) so it can be used by both the normal DMA test, and
to run the unaligned test.

Update the mxge driver.

- Update the firmware to the latest released firmware
(1.4.3), which corresponds to the firmware in the
latest shipping drivers from Myricom. This firmware
fixes several bugs in the firmware's PCI-e implementation,
and it also changes the driver/firmware interface:

o TSO was added, and changed the format of the transmit
descriptors.
o The firmware no longer counts transmits descriptors,
but frames. So the driver needs to keep a count
of the number of frames sent.
o The weird interrupt strategy changed to a normal receive
return ring. This ring is much bigger, and we may be
able to support DEVICE_POLLING.
o Myricom's header files changed the name of firmware
related #define's and enums (s/_MCP_/FW_).

- Stopped spamming the console with lots of printfs unless
mxge_verbose (or bootverbose) is set.

- Made additional information available via sysctl, including
the results of a PCI-e DMA benchmark run at device reset.

- Decreased the excessively long timeouts when sending commands
from 2 seconds to 20ms.

Please note that the files
sys/dev/myri10ge/{mcp_gen_header.h,myri10ge_mcp.h} are internally
shared between all our drivers (solaris, macosx, windows, linux, etc).
I'd like to keep these files unchanged, so I can just import newer
versions of them when the firmware API/ABI changes. This means I'm
stuck with some of the crazy-long #define names, and possibly
non-style(9) characteristics of these files.

Many thanks to mlaier for doing firmware(9) just as I
needed it, and to scottl for his helpful review.
