Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Update mxge firmware to latest available from Myricom.

Update mxge(4) firmware to 1.4.48b (latest available) from Myricom.
Pertinant highlights from Myricom CHANGES file include:

- Make sure invalid external smbus activity cannot affect performance
- Fix to avoid a bug where the link could sometimes stay reported as
up on after unplugging the cable.
- For 8B NIC, make smbus connection passive at init to avoid
possible address conflicts
- Increase number of slices to 17 for multi-slice fw
- Fix a bug where packets dropped because of link_overflow could
be occasionally reported as bad_crc32
- Add selectable failover strategy for dual-port chip: symmetric or primary/backup
- On failover, send RARP broadcast to make the change immediately
known to the network
- Change endianess for PCI Device Serial Number
- For dual-port NICs, time to failover is now a few microsecs
instead of a few millisecs.

Update mxge firmware from 1.4.39 to 1.4.43. Changes include:

- Support for 10G-PCIE*-8B*-C (dual-port CX4) NICs
- For dual-port NICs, f/w failover is now a few microsecs
instead of a few millisecs.
- On failover, f/w sends RARP broadcast to make the change
immediately known to the network
- Fixed a bug observed on IBM X3 architecture where
some spurious ecrc errors would be reported when OS enabled
ecrc support.

Better support for recent Myricom 10GbE NICs

- Update to firmware 1.4.39 for dual-chip NIC (10G-PCIE2-xxx)
support, and SFP+ i2c support

- Identify newer "B" NICs (10G-PCIEx-8B-x) correctly, rather than
mis-identifying them as "A" NICs (cosmetic only)

- Identify the IFM_10G_LRM ifmedia type, where applicable.

- Identify ifmedia types for SFP+ based NICs

- Update copyright

Update to Myri10GE Firmware 1.4.36.

This update fixes a transmit bug in the multi-queue (MSI-X) firmware
which happens when RDMAs complete out of order, and provides
improved support for the new Myri10GE NIC models (10G-PCIE-8Bx)

Update to Myri10GE firmware version 1.4.33 from 1.4.29. Relevant changes include:

- Support for Myricom 10G-PCIE-8B NICs

- multi-slice firmware: fix a bug when the presence of 32-bit or
64-bit DMA addresses for interrupt queues and data is not uniform across
slices.

- Improves automatic selection between ethp_z8e/eth_z8e

Fix accidental swap of "const" for "static" in mxge firmware byte arrays
caused by running my import script with the wrong args.

Update to firmware version 1.4.29 from 1.4.25. Relevant changes include:

- Fix a bug introduced in 1.4.20 where speculative read by the processor in the
write-only doorbell region would cause a target-abort (as opposed to simply
returning random data). This could manifest itself as NMI or machine freeze
depending on how the BIOS/OS/chipset configuration handles target-abort.

- Add support for new revisions of -R cards (with AEL1002/AEL1010 xaui->xfi)

- Increase an internal timing (dispatch engine): fix possible spurious reset
(seen on very few cards).

- Fix a bug which could cause a panic when enabling LRO
on an down mxge interface
- Fix a bug where mxge reported the link state as
active when it wasn't (after ifconfig down).
- Prevent spurious watchdog resets when link partner is not consuming
- Add support for CX4 and popular XFP media detection
- Update the firmware and associated header files to 1.4.25

Approved by: re (kensmith)

- Enable static building of mxge(4) and its firmware.

- Add custom .c wrappers for the firmware, rather than the standard
firmware(9) generated firmware objects to work around toolchain
problems on ia64 involving linking objects produced by
ld -b -binary into the kernel.

- Move from using Myricom's ".dat" firmware blobs to using Myricom's
zlib compressed ".h" firmware header files. This is done to
facilitate the custom wrappers, and saves a fair amount of wired
memory in the case where the firmware is built in, or preloaded.

- Fix two compile issues in mxge which only appear on non-i386/amd64.
